Description

i 149733in 149733

Opfindelsen angår et klæbemiddel til fastgørelse af en ostomi-pose til huden rundt om stoma hos en patient, hvilket element er af den type, der omfatter en bøjelig formstofplade med en åbning, hvorigennem stoma kan passere.The invention relates to an adhesive for attaching an ostomy bag to the skin around the stoma of a patient, which element is of the type comprising a flexible plastic sheet with an opening through which the stoma can pass.

5 Efter en ostomioperation, f.éks. ileostomi, colo- stomi eller ureterostomi, har patienten en åbning, hvorigennem der sker en udtømning. Det udtømte opsamles i en pose, som udskiftes periodisk. Der har været betydelige vanskeligheder med at sikre posens fastgørelse til pa-10 tienten på en komfortabel men tæt måde, og især har det vist sig vanskeligt at finde egnede klæbemidler til brug på klæbeelementer af den nævnte type.5 After an ostomy operation, e.g. ileostomy, colostomy or ureterostomy, the patient has an opening through which a discharge occurs. The depleted is collected in a bag which is replaced periodically. There have been considerable difficulties in securing the bag's attachment to the patient in a comfortable but dense manner, and in particular it has proved difficult to find suitable adhesives for use on adhesive elements of said type.

Selv om der kendes mange klæbemidler, er meget få af disse egnede til anvendelse på menneskehud. Kravene 15 til et sådant klæbemiddel er strenge; det skal binde kraftigt til menneskehud, men dog kunne aftrækkes uden at beskadige hudoverfladen. Endvidere må det ikke give inflammation, selv ved langvarig kontakt, og det skal have en minimal tendens til at fremkalde allergi. Det 20 skal være uden indhold af ethvert stof, som kan være carcinogent. Kravet om at det ikke må fremkalde allergi er særligt vanskeligt at opfylde, og de fleste klæbemidler, som står til rådighed, har tendens til at fremkalde allergier hos en væsentlig del af patienterne. Når pa-25 tienten har tendens til allergi, kan det være nødvendigt at prøve et antal klæbemidler, før der findes et, som er foreneligt med huden. Dette er tidskrævende for lægen, og i mellemtiden er patienten udsat for ubehag som følge af allergiske reaktioner.Although many adhesives are known, very few of these are suitable for use on human skin. The requirements of such an adhesive are strict; it must bind strongly to human skin, but could be pulled off without damaging the skin surface. Furthermore, it must not cause inflammation, even during prolonged contact, and it must have a minimal tendency to induce allergy. It must be free of any substance which may be carcinogenic. The requirement that it should not cause allergies is particularly difficult to meet, and most of the available adhesives tend to cause allergies in a significant proportion of patients. When the patient is prone to allergies, it may be necessary to try a number of adhesives before finding one that is compatible with the skin. This is time-consuming for the physician, and in the meantime, the patient is exposed to discomfort due to allergic reactions.

30 Det er fra GB-patentskrift nr. 554.186 og nr.30 It is from GB Patent No. 554,186 and no.

585.184 almindelig kendt at anvende blandinger af syntetisk gummi, fyldstof, blødgøringsmiddel og harpiks som medicinske klæbemidler, og det er desuden almindelig kendt at anvende polyalkylacrylatharpikser i medicinske 35 lægemidler.585,184 are commonly known to use blends of synthetic rubber, filler, plasticizer and resin as medical adhesives, and it is additionally well known to use polyalkyl acrylate resins in medical drugs.

Klæbeelementer med sådanne klæbemidler har imidlertid som nævnt vist sig at have tendens til at fremkalde allergi hos en væsentlig del af patienterne.However, as mentioned, adhesive elements with such adhesives have tended to induce allergy in a significant proportion of patients.

Det er endvidere fra dansk fremlæggelseskrift nr.It is furthermore from Danish submission no.

5 132.645 kendt at anvende en skive af hydrofilt materiale f.eks karayagummi, der både er klæbende og vandabsorberende, som klæbeflade i sådanne klæbeelementer.No. 5,132,645 is known to use a disc of hydrophilic material, for example, karaya gum, which is both adhesive and water-absorbent, as adhesive surface in such adhesive elements.

Sådanne klæbeelementer har imidlertid vist sig at være upålidelige, da klæbefladen, når det hydrofile ma-10 teriale har optaget en vis væskemængde, bliver blød og ikke længere kan klæbe fast til huden, herved løsnes hele klæbeelementet, hvilket er til stor gene for patienten.However, such adhesive elements have been found to be unreliable as the adhesive surface, when the hydrophilic material has absorbed a certain amount of fluid, becomes soft and can no longer adhere to the skin, thereby loosening the entire adhesive element, which is of great concern to the patient.

Heroverfor opnås med klæbeelementet ifølge op-15 findelsén et klæbeelement, der klæber godt til menneskehud, er let aftrækkeligt, og som ikke har allergene virkninger.On the contrary, with the adhesive element according to the invention, an adhesive element which adheres well to human skin is easily peelable and which does not have allergenic effects.

Ved opfindelsen tilvejebringes der et klæbeelement til fastgørelse af en ostomipose til huden rundt om 20 stoma på en patient, hvilket element omfatter en bøjelig formstofplade med en åbning, hvorigennem stoma kan passere, og er ejendommelig ved, at den flade af pladen, der skal vende mod huden, bærer et klæbemiddel, der består af en geleret blanding af: 25 a) polyethylmethacrylat, b) butyl-phthalyl-butyl-glycollat eller butyl-benzyl-phthalat, c) colloidt silica, og d) chloreret polyisopren, 30 hvorhos det pr. 100 ml komponent b) indeholder 16 - 84 g komponent a), 6 - 16 g komponent c) og 16 -67 g komponent d).The invention provides an adhesive element for attaching an ostomy bag to the skin around 20 stoma on a patient, which element comprises a flexible plastic sheet having an opening through which the stoma can pass, and is characterized in that the surface of the plate to be turned bears an adhesive consisting of a gelled mixture of: a) polyethyl methacrylate, b) butyl phthalyl butyl glycolate or butyl benzyl phthalate, c) colloidal silica, and d) chlorinated polyisoprene, wherein per. 100 ml of component b) contains 16 - 84 g of component a), 6 - 16 g of component c) and 16 - 67 g of component d).

Polyethylmethacrylatet er et skørt fast stof, som fortrinsvis har en molekylvægt i området 50.000-35 1.000.000, mere foretrukket i området 100.000-500.000, f.eks. ca. 200.000.The polyethyl methacrylate is a brittle solid which preferably has a molecular weight in the range 50,000-35,000,000, more preferably in the range 100,000-500,000, e.g. ca. 200,000.

149733 3149733 3

Butyl-phthalyl-butyl-glycollat eller butyl-ben-zyl-phthalat er en blødgøringskomponent. Denne er en væske, som er fysiologisk tålelig, og som tjener til at blødgøre polyethylmethacrylatet. Butyl-phthalyl-butyl-5 glycollat og butylbenzylphthalat kan fås fra Monsanto som henholdsvis "Santicizer R B16" og "Santicizer R 160".Butyl-phthalyl-butyl-glycollate or butyl-benzyl-phthalate is a softening component. This is a physiologically tolerable liquid which serves to soften the polyethyl methacrylate. Butyl phthalyl butyl glycollate and butyl benzyl phthalate are available from Monsanto as "Santicizer R B16" and "Santicizer R 160" respectively.

Disse blødgøringsmidler er fysisk forenelige med de andre komponenter i midlet og er fysiologisk tåle-10 ligt, herunder non-allergene.These plasticizers are physically compatible with the other components of the agent and are physiologically tolerable, including non-allergenic.

Colloidt silica er et indifferent partikkelfor-met fyldstof, der tjener til at stabilisere midlet i form af en sammenhængende gel. Fyldstoffet formindsker også midlets klæbrighed, og mængden og arten af fyld-15 stoffet skal vælges, således at der frembringes den krævede grad af klæbrighed. Uden fyldstof er klæbningen meget kraftig, og adhesionen til den menneskelige hud er vanskelig at bryde uden at beskadige huden.Colloidal silica is an inert particulate filler which serves to stabilize the agent in the form of a coherent gel. The filler also decreases the tackiness of the agent and the amount and nature of the filler must be selected so as to produce the required degree of tackiness. Without filler, the adhesive is very strong and the adhesion to the human skin is difficult to break without damaging the skin.

Den chlorerede polyisopren forbedrer klæbrigheden 20 og sammenhængsevnen for midlet. Foretrukne chlorerede polyisopren-typer er kraftigt chlorerede polyisoprener såsom den højt chlorerede polyisopren, som fås fra Imperial Chemical Industries som "Alloprene R 20".The chlorinated polyisoprene improves the tackiness and cohesiveness of the agent. Preferred chlorinated polyisoprene types are highly chlorinated polyisoprene such as the highly chlorinated polyisoprene available from Imperial Chemical Industries as "Alloprene R 20".

Mængden af de forskellige komponenter i midlet 25 er pr. 100 ml butyl-phthalyl-butyl-glycollat eller bu-tyl-benzyl-phthalat ifølge opfindelsen som følger: Polyethylmethacrylat 16-84 g, fortrinsvis 20-45 g, silica 6-16 g, fortrinsvis 8-12 g, og chloreret gummi 16-67 g, fortrinsvis 20-40 g. De relative forhold mellem 30 mængderne skal indstilles inden for disse intervaller til opnåelse af produkter med de ønskede egenskaber. De optimale indbyrdes forhold til opnåelse af enhver specielt ønsket kombination af egenskaber kan bestemmes ved simple eksperimenter.The amount of the various components of the agent 25 is 100 ml of butyl-phthalyl-butyl-glycollate or butyl-benzyl-phthalate according to the invention as follows: Polyethyl methacrylate 16-84 g, preferably 20-45 g, silica 6-16 g, preferably 8-12 g, and chlorinated rubber 16 -67 g, preferably 20-40 g. The relative ratios of the 30 amounts must be adjusted within these ranges to obtain products having the desired properties. The optimum interrelationships for obtaining any particularly desired combination of properties can be determined by simple experiments.

35 Midlet kan fremstilles ved at dispergere og oplø se polyethylmethacrylatet, i pulverform, i blødgørings- 149733 4 midlet til dannelse af en gel. Fyldstoffet og det chlo-rerede gummi kan tilsættes på ethvert trin, fortrinsvis medens viskositeten stadig er tilstrækkelig lav til at muliggøre en grundig blanding. Ved en foretrukken blan-5 dingsmetode blandes fyldstoffet med blødgøringsmidlet, hvorpå polyethylmethacrylatet tilsættes, hvorefter til slut det chlorerede gummi tilsættes.The agent may be prepared by dispersing and dissolving the polyethyl methacrylate, in powder form, in the plasticizer to form a gel. The filler and chlorinated rubber can be added at any stage, preferably while the viscosity is still sufficiently low to allow a thorough mixing. In a preferred blending method, the filler is mixed with the plasticizer to which the polyethyl methacrylate is added, and finally the chlorinated rubber is added.

Blandingen er initialt en stiv pasta, som omdannes til en homogen gel, når blødgøringsmidlet opløser 10 polyethylmethacrylatet. Denne omdannelse forløber langsomt ved stuetemperatur og accelereres ved opvarmning, f.eks. til 40-80°C. Højere eller lavere temperaturer kan anvendes, hvor dette er bekvemt. Ved 60°C kan omdannelsen typisk afsluttes i løbet af 4-5 timer. Omdannelses-15 tiden afhænger i høj grad af, hvor findelt polyethylmethacrylatet er. Fortrinsvis anvendes dette materiale i form af et pulver i området 50-400 mesh (britisk standard sigte), fortrinsvis under 200 mesh.Initially, the mixture is a rigid paste which is converted to a homogeneous gel when the plasticizer dissolves the polyethyl methacrylate. This conversion proceeds slowly at room temperature and is accelerated by heating, e.g. to 40-80 ° C. Higher or lower temperatures can be used where this is convenient. At 60 ° C, the conversion can typically be completed in 4-5 hours. The conversion time depends to a large extent on how finely divided the polyethyl methacrylate is. Preferably, this material is used in the form of a powder in the range of 50-400 mesh (British standard sieve), preferably below 200 mesh.

Efter omdannelsen er midlet en halvgennemsigtig 20 flexibel gel med gummiagtig konsistens, og det føles klæbrigt. Det har god adhesion til menneskehud. Materialet er stabilt, dvs. det forbliver sammenhængende, flyder ikke ud, og det har stor koncentration af fyldstof og bevarer sin klæbrighed og adhesivitet efter langvarig 25 lagring og anvendelse.After the transformation, the agent is a semi-transparent flexible gel with a rubbery consistency and it feels sticky. It has good adhesion to human skin. The material is stable, ie. it remains coherent, does not flow out, and has high concentration of filler and retains its tackiness and adhesiveness after prolonged storage and use.

Det er ofte bekvemt at overføre midlet i geltilstand in situ på overfladen, som skal gøres klæbende. Alternativt kan midlet før omdannelsen udspredes på en overflade med et overtræk af et slipmiddel og overføres 30 i geltilstand i form af et lag, som derpå kan lamineres på den artikel, der skal gøres klæbende. En anden måde at påføre midlet på er at danne en dispersion af midlet i et organisk opløsningsmiddel, som opløser alle midlets komponenter bortset fra fyldstoffet, f.eks. et chloreret 35 carbonhydrid, så som chloroform eller methylendichlorid, 149733 5 påføre dispersionen på en genstand, som skal gøres klæbende, og afdampe opløsningsmidlet. Andre egnede opløsningsmidler er lavere aliphatiske ketoner, f.eks. acetone, aliphatiske ethere, f.eks. diethylether, og lavere 5 alkanoler, f.eks. ethanol. Ofte vil man foretrække at undgå anvendelse af et opløsningsmiddel, da nogle patienter udviser allergiske reaktioner mod almindelige organiske opløsningsmidler. Derfor kan det være fordelagtigt at udvalse midlet i pastaform til et tyndt lag mel-10 lem overflader med et som sliplag virkende overtræk, og påføre midlet på den genstand, som skal gøres klæbende, enten før eller efter omdannelse af blandingen til en gel.It is often convenient to transfer the gel in situ to the gel on the surface which must be made adhesive. Alternatively, before the conversion, the agent may be spread on a surface of a release agent and transferred in a gel state in the form of a layer which may then be laminated to the article to be adhered. Another way of applying the agent is to form a dispersion of the agent in an organic solvent which dissolves all the components of the agent except the filler, e.g. a chlorinated hydrocarbon, such as chloroform or methylene dichloride, apply the dispersion to an article to be adhered and evaporate the solvent. Other suitable solvents are lower aliphatic ketones, e.g. acetone, aliphatic ethers, e.g. diethyl ether, and lower alkanols, e.g. ethanol. Often, it is preferable to avoid the use of a solvent as some patients exhibit allergic reactions to common organic solvents. Therefore, it may be advantageous to select the agent in paste form into a thin layer between surfaces with a coating-like coating, and apply the agent to the article to be adhered, either before or after conversion of the mixture to a gel.

Den anden flade på klæbeelementet kan være inte-15 gral med en af posens vægge, eller posen kan være fastgjort hertil på passende mekanisk måde, f.eks. ved hjælp af et klæbemiddel.The second surface of the adhesive element may be integral with one of the walls of the bag, or the bag may be attached thereto in an appropriate mechanical manner, e.g. using an adhesive.

Pladen, som sædvanligvis vil have form af en skive med en central åbning, er af formstof. Egnede form-20 stoffer omfatter blødgjorte acrylpolymere og blødgjorte vinylpolymere, såsom blødgjort PVC. Da dele af pladen kan komme i kontakt med patienten, er det tilrådeligt, at den fremstilles af et materiale, som ikke har tendens til at fremkalde nogen uheldig reaktion ved kontakt med 25 det menneskelige legeme. Specielt skal materialet være non-allergent. Egnede formstofmaterialer kan udvælges blandt sådanne, som anvendes indenfor dentalområdet.The plate, which will usually take the form of a disc with a central opening, is made of plastic. Suitable molds include plasticized acrylic polymers and plasticized vinyl polymers such as plasticized PVC. Since parts of the plate can come into contact with the patient, it is advisable that it be made of a material which does not tend to cause any adverse reaction upon contact with the human body. In particular, the material must be non-allergic. Suitable resin materials can be selected from those used in the dental field.

Enhver accelerator (f.eks. tertær amin, peroxid eller quinon), som anvendes til hærdning af det materiale, som 30 danner pladen, skal udvælges under særlig iagttagelse af dette synspunkt. Det kan være fordelagtigt at hærde materialet ved hjælp af actinisk stråling (ultraviolet eller synligt lys).Any accelerator (e.g., tertiary amine, peroxide or quinone) used to cure the material forming the plate must be selected with particular regard to this point of view. It may be advantageous to cure the material by actinic radiation (ultraviolet or visible light).

Det er fordelagtigt, at den del af pladen, som .35 omgiver åbningen, er relativt stiv, medens den perifere 149733 6 del er mere bøjelig. Disse betingelser kan opnås ved at forøge tykkelsen af pladen i det centrale område og/el-ler ved at anvende et eller flere afstivende væv rundt om åbningen. Imidlertid skal pladen som helhed være til-5 strækkelig bøjelig for at undgå, at den giver patienten ubehag, og for at opnå, at den slutter tæt til underlivet.Advantageously, the portion of the plate surrounding the aperture is relatively rigid, while the peripheral portion is more flexible. These conditions can be achieved by increasing the thickness of the plate in the central region and / or by using one or more stiffening tissues around the aperture. However, the plate as a whole must be sufficiently flexible to prevent it from causing discomfort to the patient and to ensure that it joins close to the abdomen.

Pladens anden flade kan være udformet integralt med ostomiposen, eller posen kan være fastgjort på pas-10 sende mekanisk måde, f.eks. med hægter eller mere foretrukket med klæbemiddel. Denne side af posen kommer ikke i kontakt med huden, og ethvert egnet klæbemiddel kan anvendes. Det er ikke nødvendigt, at dette klæbemiddel kan tåles fysiologisk, men ofte vil det samme klæbemid-15 del være velegnet til formålet.The second surface of the plate may be integrally formed with the ostomy bag, or the bag may be secured in a suitable mechanical manner, e.g. with hooks or more preferably with adhesive. This side of the bag does not come into contact with the skin and any suitable adhesive can be used. It is not necessary that this adhesive can be tolerated physiologically, but often the same adhesive will be suitable for the purpose.

Klæbemidlet, der ifølge opfindelsen bæres på pladens ene flade, kan i form af et sammenhængende lag strække sig ud over pladens periferi, og den fri flade af klæbemiddellaget kan bidrage til at fastholde posen 20 på pladen. Hvis den ikke anvendes til dette formål, er det hensigtsmæssigt at gøre denne blottede flade og kanterne af klæbemiddellaget ikke-klæbende for at undgå vedhæftning til tøj og lignende.The adhesive carried according to the invention on one face of the sheet can extend in the form of a continuous layer over the periphery of the sheet, and the free surface of the adhesive layer can help to retain the bag 20 on the sheet. If not used for this purpose, it is advisable to render this exposed surface and the edges of the adhesive layer non-adhesive to avoid adhesion to clothing and the like.

Ved en foretrukken udførelsesform kan posen til 25 opsamling af udtømning fra stoma udskiftes uden fjernelse af pladen fra patienten. Dette overflødiggør afrivning af hele enheden fra patienten hver dag. Denne udførelsesform er særligt anvendelig i forbindelse med colo-stomiposer. Ved denne udførelsesform er posen fortrins-30 vis fastgjort til pladen ved hjælp af et kontaktklæbe-middel.In a preferred embodiment, the bag for collecting discharge from the stoma can be replaced without removing the plate from the patient. This eliminates tearing of the entire device from the patient every day. This embodiment is particularly useful in connection with colo-ostomy bags. In this embodiment, the bag is preferably attached to the plate by a contact adhesive.

Den ovenfor beskrevne udførelsesform er særligt egnet til ostomipatienter, men kan også være af værdi til opsamling af fisteludflåd.

Surgically, an adhesive member comprises a disc 3 of plastic with a central opening 4. The opening 4 is surrounded by 2 concentric webs 5 and 6 forming a gutter. , which contains a ring of karaya rubber 7. According to the invention, the outer part of the disc is attached to the abdomen wall with a layer of adhesive 8 having the composition given below. The second surface 9 of the disc is provided for attaching a bag suitable for the discharge to be collected.

20 Klæbemidlet strækker sig noget ud over skiven 3 for herved at holde enheden i god kontakt med underlivsvæggen .The adhesive extends slightly beyond the disc 3 to thereby keep the unit in good contact with the abdominal wall.

Klæbemidlets sammensætning er som følger, idet dele refererer til ml for såvidt angår væsker og til g 25 for såvidt angår faste stoffer:The composition of the adhesive is as follows, parts referring to ml as far as liquids are concerned and to g 25 as far as solids are concerned:

Butyl-phthalyl-butyl-glycolat 6 deleButyl-phthalyl-butyl-glycolate 6 parts

Polyethyl-methacrylat 2 dele "Alloprene®20" 2 delePolyethyl methacrylate 2 parts "Alloprene®20" 2 parts

Colloidt silica 0,65 dele 30 Butyl-phthalyl-butyl-glycolatet er tilgængeligt fra Monsanto som "Santicizer ® B16". løvrigt kan det fremstilles efter standardesterificeringsmetoder.Colloidal silica 0.65 parts 30 The butyl phthalyl butyl glycolate is available from Monsanto as "Santicizer ® B16". leafy it can be prepared by standard esterification methods.

Polyethyl-methacrylatet havde form af et pulver med en partikelstørrelse under 240 mesh (britisk stan-35 dard sigte) og havde en gennemsnitlig molekylvægt på ca.The polyethyl methacrylate was in the form of a powder having a particle size of less than 240 mesh (British standard sieve) and had an average molecular weight of approx.

"Alloprene® 20" er en chloreret polyisopren, som fås fra Imperial Chemical· Industries, (Alloprene Sec-5 tion), Runcorn, Cheshire, England."Alloprene® 20" is a chlorinated polyisoprene available from Imperial Chemical · Industries, (Alloprene Sec-5 tion), Runcorn, Cheshire, England.

Silicaet var af farmaceutisk kvalitet med lavt jernindhold.The silica was of low iron pharmaceutical quality.

Først blev silicaet blandet med butyl-phthalyl-butyl-glycolat, og polyethyl-metalcrylatet og “Allo-10 prene® " blev derpå tilsat i rækkefølge. Der fremkom en meget viskos pasta, som blev blandet mekanisk. Pastaen blev derpå udvalset mellem to lag siliconeovertrukne papirark til en tykkelse på ca. 1,5 mm og henstillet til omdannelse i 6 timer i en ovn ved 60°C.First, the silica was mixed with butyl-phthalyl-butyl glycolate, and then the polyethyl-metal acrylate and "Allo-10prene®" were added sequentially. A very viscous paste was obtained which was mixed mechanically. The paste was then rolled between two layers. silicone coated paper sheets to a thickness of about 1.5 mm and allowed to convert for 6 hours in an oven at 60 ° C.

15 Efter afkøling forelå klæbemidlet som et sammen hængende, særdeles klæbrigt lag, som kunne skæres i den ønskede størrelse og facon. Dette klæbemiddel tåles særdeles godt af det menneskelige legeme. Faktisk er der ikke hidtil iagttaget nogen uheldlig reaktion over for 20 det selv hos patienter, som er allergiske over for mange sædvanlige medicinske klæbmidler.After cooling, the adhesive was available as a cohesive, highly adhesive layer that could be cut to the desired size and shape. This adhesive is very well tolerated by the human body. Indeed, so far no adverse reaction to 20 has been observed even in patients who are allergic to many common medical adhesives.

En anden klæbemiddelsammensætning er som følger:Another adhesive composition is as follows:

Butyl-benzyl-phthalat 6 mlButyl benzyl phthalate 6 ml

Polyethyl-methacrylat 2 g 25 "Alloprene®20" 2 gPolyethyl methacrylate 2 g 25 "Alloprene® 20" 2 g

Colloid silica 0,5 gColloid silica 0.5 g

Polyethyl-methacrylatet var det samme som blev anvendt i det første klæbemiddel. Blande- og omdannelsesproceduren var som beskrevet.The polyethyl methacrylate was the same as used in the first adhesive. The mixing and conversion procedure was as described.

30 Skiven var dannet af en acrylpolymer, som var fremstillet som følger. 16 dele af det ovenfor beskrevne polyethyl-methacrylat blev blandet med 10 dele af en flydende blanding med sammensætningen 2% N,N-dimethyl-p-toluidin, 30% ethylen-glycol-dimethacrylat (fra Rohm & 35 Haas) og 68% butyl-phthalylbutyl-glycollat.The disc was formed from an acrylic polymer prepared as follows. 16 parts of the above-described polyethyl methacrylate were mixed with 10 parts of a liquid mixture of the composition 2% N, N-dimethyl-p-toluidine, 30% ethylene-glycol dimethacrylate (from Rohm & 35 Haas) and 68% butyl -phthalylbutyl glycollate.

Den resulterende fluide opslemning blev straks hældt i en form og hærdet i 15 minutter ved 60°C til dannelse af en flexibel gummiagtig skive. Acceleratoren (Ν,Ν-dimethyl-p-toluidin) kan erstattes af andre egnede 5 tertiære aminer, men dette materiale skal fortrinsvis udvælges under hensyntagen til, at allergiproblemer skal undgås.The resulting fluid slurry was immediately poured into a mold and cured for 15 minutes at 60 ° C to form a flexible rubbery disc. The accelerator (Ν, Ν-dimethyl-p-toluidine) may be replaced by other suitable tertiary amines, but this material should preferably be selected taking into account that allergy problems should be avoided.
