Description
Foreliggende oppfinnelse angår varmebestandig plast på basis av en vinylkloridpolymer. The present invention relates to heat-resistant plastic based on a vinyl chloride polymer.
Det er kjent at polymerer og kopolymerer av vinylklorid anvendes for fremstilling av ferdige gjenstander ved ulike prosesser slik som forming, pressing, sprøyting og støping, noe som krever høye temperaturer for at polymeren skal oppnå en tilstrekkelig mykhetsgrad. Ved disse temperaturer som kan gå helt opp til l80-200°C, skjer det i polymerer på basis av vinylklorid en betydelig nedbryting som fører til en forandring av fargen og de mekaniske egenskaper. Por å unngå denne forandring har man foreslått tilsetning av varmestabiliserihgs-midler slik som metallchelater av dikarbonylforbindelser, enten alene eller i kombinasjon med karboksylsyresalter av slike metaller som kalsium, bly og kadmium (US-patenter nr. 2307075 og 2669548). Man har også anvendt salter av tung-metaller og høyere fettsyrer i kombinasjon med organiske fos-fitter (US-patent nr. 2564646) eller i kombinasjon med poly-oler (US-patent nr. 2711401). Disse forskjellige midler er imidlertid ikke tilstrekkelige når polymeren utsettes for høye temperaturer og anvendes for fremstilling av lyse eller gjennomskinnelige gjenstander fordi også en tilfeldig kraftig oppvarming fremkaller en mer eller mindre kraftig gulning av polymeren slik at denne blir uanvendelig for visse formål. It is known that polymers and copolymers of vinyl chloride are used for the production of finished articles by various processes such as forming, pressing, spraying and casting, which require high temperatures for the polymer to achieve a sufficient degree of softness. At these temperatures, which can go all the way up to 180-200°C, a significant breakdown occurs in polymers based on vinyl chloride, which leads to a change in the color and the mechanical properties. In order to avoid this change, it has been proposed to add heat stabilizing agents such as metal chelates of dicarbonyl compounds, either alone or in combination with carboxylic acid salts of such metals as calcium, lead and cadmium (US patents no. 2307075 and 2669548). Salts of heavy metals and higher fatty acids have also been used in combination with organic phosphites (US patent no. 2564646) or in combination with polyols (US patent no. 2711401). However, these various means are not sufficient when the polymer is exposed to high temperatures and is used for the production of light or translucent objects, because even an accidental strong heating causes a more or less strong yellowing of the polymer so that it becomes unusable for certain purposes.
Ved fremstilling av gjennomskinnelige filmer eller hinner When producing translucent films or membranes
eller ved fremstilling av flasker og liqnende kan man således ikke godta en forandring av polymerens farge ettersom dette vil gjøre gjenstandens gjennomskinnelighet dårligere. Man har nu funnet at det er mulig å forhindre denne termiske nedbrytning av polymerblandinger på basis av vinylklorid ved tilsetning av or in the production of bottles and the like, a change in the polymer's color cannot therefore be accepted as this will make the object's translucency worse. It has now been found that it is possible to prevent this thermal decomposition of polymer mixtures based on vinyl chloride by adding
foreliggende stabiliseringsmiddelblanding. present stabilizer mixture.

Med polymerblandinger på basis av polyvinylklorid mener man blandinger inneholdende en homopolymer eller en kopolymer av vinylklorid pluss forskjellige slike tilsetningsstoffer som vanligvis benyttes for å lette blandingenes anvendelse eller for å gi de ferdige produkter spesielle egenskaper. By polymer mixtures based on polyvinyl chloride is meant mixtures containing a homopolymer or a copolymer of vinyl chloride plus various such additives which are usually used to facilitate the use of the mixtures or to give the finished products special properties.
Alle typer av homopolymerer av vinylklorid kan anvendes, uavhengig av fremgangsmåten for fremstillingen, som kan skje ved massepolymerisering, suspensjonspolymerisering, emulsjonspolymerisering eller på annen måte. All types of homopolymers of vinyl chloride can be used, regardless of the method of production, which can take place by mass polymerisation, suspension polymerisation, emulsion polymerisation or in another way.
Mange forskjellige kopolymerer av vinylklorid kan gjøres varmebestandige på samme måte som homopolymerene. Kopolymerene kan f.eks. være fremstilt ved kopolymerisering av vinylklorid med andre monomerer inneholdende en polymeriserbar eten-isk binding, slik som eten, akrylestere, styren, vinylestere, Many different copolymers of vinyl chloride can be made heat resistant in the same way as the homopolymers. The copolymers can e.g. be produced by copolymerization of vinyl chloride with other monomers containing a polymerizable ethylenic bond, such as ethylene, acrylic esters, styrene, vinyl esters,
maleinsyre eller maleinsyreanhydrid, maleinsyreestere. maleic acid or maleic anhydride, maleic acid esters.
Kopolymerene inneholder minst 50 vekt-% vinylklorid. Ifølge oppfinnelsen anvendes fortrinnsvis kopolymerer som inneholder minst 80 vekt-% vinylklorid og hvis andre monomerer er vinylacetat eller vinylidenklorid. Disse kopolymerer kan anvendes alene eller i blanding med andre polymerer, spesielt med polyvinylklorider. The copolymers contain at least 50% by weight of vinyl chloride. According to the invention, copolymers are preferably used which contain at least 80% by weight of vinyl chloride and whose other monomers are vinyl acetate or vinylidene chloride. These copolymers can be used alone or in admixture with other polymers, especially with polyvinyl chlorides.
Man kan også ifølge oppfinnelsen stabilisere blandinger på basis av overklorerte polyvinylklorider hvis klorinnhold kan gå opp til 65-70$, forbindelser som er meget følsomme for termisk nedbrytning når de underkastes høye temperaturer. According to the invention, it is also possible to stabilize mixtures based on overchlorinated polyvinyl chlorides whose chlorine content can go up to 65-70%, compounds which are very sensitive to thermal decomposition when subjected to high temperatures.
Karboksylsyresaltene av to-verdige metaller er fortrinnsvis salter av kalsium, barium, sink, bly eller kadmium med mettede eller umettede alifatiske syrer eller med aromatiske syrer. Blant disse salter kan nevnes acetater, diacetater, etylheksanoater, oktoater, stearater, oleater, laurater, palmitater, myristater, ricinoleater, benzoater og ftalater. Saltene anvendes vanligvis i form av blandinger på The carboxylic acid salts of divalent metals are preferably salts of calcium, barium, zinc, lead or cadmium with saturated or unsaturated aliphatic acids or with aromatic acids. Among these salts may be mentioned acetates, diacetates, ethyl hexanoates, octoates, stearates, oleates, laurates, palmitates, myristates, ricinoleates, benzoates and phthalates. The salts are usually used in the form of mixtures of
to og to salter, f.eks. kalsiumsalter og sinksalter. Por fremstilling av næringsmiddelforpakninger eller flasker er det spesielt egnet å anvende salter av jordalkalimetaller og fettsyrer med lange kjeder etter som den slags salter er ugif-tige og har en smørende virkning. Spesielt skal nevnes stearater, laurater og 2-etylheksanoater av kalsium og av sink. Disse salter anvendes som nevnt i en mengde på 0,1-5% regnet på polymerens vekt. two and two salts, e.g. calcium salts and zinc salts. For the production of food packaging or bottles, it is particularly suitable to use salts of alkaline earth metals and fatty acids with long chains, as such salts are non-toxic and have a lubricating effect. Particular mention should be made of stearates, laurates and 2-ethyl hexanoates of calcium and of zinc. As mentioned, these salts are used in an amount of 0.1-5% calculated on the weight of the polymer.
De dikarbonylforbindelser med formelen I som ifølge oppfinnelsen anvendes sammen med nevnte metallsalter kan være 3-diketoner. Dikarbonylforbindelsene kan også være 3- keto-aldehyder, når et av symbolene R-^ og FU i formelen I angir et hydrogenatom. The dicarbonyl compounds of the formula I which according to the invention are used together with said metal salts can be 3-diketones. The dicarbonyl compounds can also be 3-keto-aldehydes, when one of the symbols R-^ and FU in formula I denotes a hydrogen atom.
5- diketoner er kjente forbindelser som fremstilles ifølge kjente synteser. Man kan f.eks. hevise til "Organic Reactions" av R. Adams, 1951*, VIII, side 59 og følgende. Visse mere spesifikke synteser beskrives i "Ree. Trav. Chem. Pays-Bas" av M.J.' Kramers, 16 (1897) side 116; i "J. Chem. Soc." av G.T. Morgan og E. Holmes, 127 (1925) side 2891; i "J. Chem. Soc." av R. Robinson og E. Seijo (1941), side 582; samt i "Chemisene Berichte" av Claisen, 20 (1887) side.2188. 5-diketones are known compounds which are prepared according to known syntheses. One can e.g. refer to "Organic Reactions" by R. Adams, 1951*, VIII, page 59 et seq. Certain more specific syntheses are described in "Ree. Trav. Chem. Pays-Bas" by M.J.' Kramers, 16 (1897) page 116; in "J. Chem. Soc." by G.T. Morgan and E. Holmes, 127 (1925) page 2891; in "J. Chem. Soc." by R. Robinson and E. Seijo (1941), page 582; as well as in "Chemisene Berichte" by Claisen, 20 (1887) page.2188.
6- keto-aldehydene fremstilles ifølge klas- The 6-keto-aldehydes are prepared according to class
siske syntesemetoder slik man f.eks. kan finne det nevnt i det ovenfor angitte verk "Organic Reactions" av R. Adams, side 59 sic synthesis methods such as e.g. can find it mentioned in the above mentioned work "Organic Reactions" by R. Adams, page 59
og følgende. and the following.
Disse organiske forbindelser anvendes i en mengde på 0,05 til 5%, fortrinnsvis 0,1-1%, beregnet på polymerens vekt. These organic compounds are used in an amount of 0.05 to 5%, preferably 0.1-1%, calculated on the weight of the polymer.
Som eksempler på slike forbindelser skal nevnes alifatiske 3-diketoner slik som hepatan-2,4-dion, dekan-2,4-dion, etyl-nonan(2,4-dion)karboksylat, 8-metyl-7-nonen-2,4-dion, acyloksyacetoner slik som acetylaceton, 1,1-diacetyl-acton eller triacetylmetan, stearoylaceton, stearoylalkanoner. Man kan også nevne aromatiske eller arylalifatiske 3-diketoner, slik som benzoylaceton, tribenzoylmetan, diacetylacetobenzener, stearoylacetofenon og palmitoylacetofenon. Por å oppnå en langvarig stabiliserende virkning er det spesielt hensikts-messig å anvende diketoner som inneholder en lang alkylkjede slik som stearoylaceton, palmitoylaceton, laurylaceton, stearoylacetofenon, palimitoylacetofenon og laurylacetofenon. Examples of such compounds include aliphatic 3-diketones such as hepatane-2,4-dione, decane-2,4-dione, ethyl nonane (2,4-dione) carboxylate, 8-methyl-7-nonen-2 ,4-dione, acyloxyacetones such as acetylacetone, 1,1-diacetylacetone or triacetylmethane, stearoylacetone, stearoylalkanones. One can also mention aromatic or arylaliphatic 3-diketones, such as benzoylacetone, tribenzoylmethane, diacetylacetobenzenes, stearoylacetophenone and palmitoylacetophenone. In order to achieve a long-term stabilizing effect, it is particularly appropriate to use diketones containing a long alkyl chain such as stearoylacetone, palmitoylacetone, laurylacetone, stearoylacetophenone, palimitoylacetophenone and laurylacetophenone.
Blant (3-keto-aldehydene kan man nevne 2-acyloksyacetaldehyder, 2-acyloksypropionaldehyder, slik som benzoylacetaldehyd og 2-acetyl-2-metylacetalaldehyd. Among the (3-keto-aldehydes, one can mention 2-acyloxyacetaldehydes, 2-acyloxypropionaldehydes, such as benzoylacetaldehyde and 2-acetyl-2-methylacetaldehyde.
De anvendte homopolymerer eller kopolymerer kan være stive eller bøyelige. Når man anvender stive polymerer, kan man til disse sette midler som modifiserer slagfastheten, f.eks. kopolymerer av butadien og styren eller terpolymerer av butadien, styren og akrylnitril, hvilke ofte anvendes, for å for-bedre polymerenes mekaniske egenskaper. Man kan også til blandingene ifølge oppfinnelsen sette forskjellige tilsetnings-midler slik som mykningsmidler, pigmenter, fyllstoffer, anti-oksydanter, midler som gir lysbestandighet osv. The homopolymers or copolymers used can be rigid or flexible. When rigid polymers are used, agents can be added to these that modify the impact resistance, e.g. copolymers of butadiene and styrene or terpolymers of butadiene, styrene and acrylonitrile, which are often used to improve the polymers' mechanical properties. Various additives can also be added to the mixtures according to the invention, such as softeners, pigments, fillers, antioxidants, agents that provide light resistance, etc.
Det er også mulig å sette andre organiske forbindelser som er kjent for sin stabiliserende virfcning til stabiliseringsmidlene ifølge oppfinnelsen, f.eks. pentaerytritol eller trihydroksyetylisocyanurat. It is also possible to add other organic compounds which are known for their stabilizing effect to the stabilizing agents according to the invention, e.g. pentaerythritol or trihydroxyethyl isocyanurate.
Stabiliseringsmidlene ifølge oppfinnelsen kan tilsettes samtidig med de andre tilsetningsstoffer. De kan også blandes innbyrdes, enten alene eller sammen med visse tilsetningsstoffer. Herved oppnås en stabiliserende blanding som senere blandes med polyvinylklorid. Alle vanlige kjente metoder kan anvendes for å blande de forskjellige bestanddeler. Blandingen ifølge oppfinnelsen homogeniseres imidlertid hensikts-messig i et blandingsvalseverk. The stabilizers according to the invention can be added at the same time as the other additives. They can also be mixed together, either alone or together with certain additives. This results in a stabilizing mixture which is later mixed with polyvinyl chloride. All commonly known methods can be used to mix the various components. The mixture according to the invention is, however, suitably homogenized in a mixing rolling mill.
Polymerblandingene ifølge oppfinnelsen kan bearbeides og formes ifølge de fremgangsmåter som vanligvis anvendes for blandinger på basis .av polymerer eller kopolymerer av vinylklorid, f.eks. formsprøyting, strengesprøytning, strenge-sprøyting-blåsing, kalandrering, rotasjonsforming osv. The polymer mixtures according to the invention can be processed and shaped according to the methods that are usually used for mixtures based on polymers or copolymers of vinyl chloride, e.g. injection molding, string injection, string-injection-blowing, calendering, rotational molding, etc.
Kombinasjonen av et organisk stabiliseringsmiddel og et par av metalliske stabiliseringsmidler gjør det mulig å forsinke polymerblandingens gulning og å fremstille sluttproduk-ter som er gjennomskinnelige og homogene og som ikke oppviser utsvetting. The combination of an organic stabilizer and a pair of metallic stabilizers makes it possible to delay the yellowing of the polymer mixture and to produce final products which are translucent and homogeneous and which do not show sweating.
Oppfinnelsen skal illustreres ved følgende eksempler . The invention shall be illustrated by the following examples.

Av forsøksresultatene fremgår det at prøvestykkene som er fremstilt ved å : gå ut fra mykgjorte PVC-blandinger er meget mindre følsomme for gulning enn prøvestykker som er fremstilt av ikke, mykgjorte blandinger. Ved innblanding av et organisk stabiliseringsmiddel kan man dessuten ytterlig-ere redusere gulningen kraftig under en varmebehandling som til-svarer anvendelsen av blandingene. From the test results, it appears that the test pieces produced by: starting from softened PVC mixtures are much less sensitive to yellowing than test pieces produced from non-plasticized mixtures. By mixing in an organic stabilizer, the yellowing can also be greatly reduced during a heat treatment that corresponds to the use of the mixtures.
