Beschreibung description
Es wurde gefunden, dass man Methylmethacrylat-Polymere und -Copolymere sehr gut gegen die zerstörende Wirkung von Sonnenlicht schützen und gleichzeitig die Entflammbarkeit herabsetzen kann, wenn man diesen Polymeren a) eine Oxalsäureanilid- oder 2,2,6,6-Tetramethylpiperidinverbindung (Komponente a) als Stabilisator gegen die Lichtschädigung und b) eine flammhemmende organische Phosphor-Verbindung (Komponente b) It has been found that methyl methacrylate polymers and copolymers can be protected very well against the destructive effects of sunlight and at the same time reduce the flammability if these polymers a) are treated with an oxalic acid anilide or 2,2,6,6-tetramethylpiperidine compound (component a ) as a stabilizer against light damage and b) a flame-retardant organic phosphorus compound (component b)
Wohl sind z.B. aus Europ.OS 16 870 Poiymethylmethacrylate bekannt, denen zur Verhinderung der Lichtschädigung Tetraalkylpiperidyi-Verbindungen zugesetzt wurden. Andererseits sind z.B. aus DE-OS 3 510 417 Methylmethacrylat-Polymer- und -Copolymermassen bekannt, die ausgewählte, organische Phosphorverbindungen als Flammschutzmittel enthalten. For example, from Europ.OS 16 870 Poiymethylmethacrylate known to which tetraalkylpiperidyi compounds were added to prevent light damage. On the other hand, e.g. known from DE-OS 3 510 417 methyl methacrylate polymer and copolymer compositions which contain selected organic phosphorus compounds as flame retardants.
Die Kombination von Phosphorverbindungen, insbesondere Halogen enthaltenden Phosphorverbindungen als Flammschutzmittel und Tetraalkylpiperidinverbindungen als Lichtstabilisatoren ergibt in Poly-alkylenen, insbesondere Polypropylen, und in ABS sehr unbefriedigende Resultate: Die Phosphorverbindungen wirken auf die Lichtschutzmittel neutralisierend, das heisst die lichtschützende Wirkung vermindert sich, bzw. wird gänzlich aufgehoben, in einigen Fällen tritt sogar eine Gelbfärbung der Kunststoffe auf. Es war daher überraschend zu finden, dass die bekannten negativen Effekte einer Kombination von Flammschutz- und Lichtschutzmitteln in Methylmethacrylat-Polymeren und -Copolyme-ren nicht auftreten. The combination of phosphorus compounds, in particular halogen-containing phosphorus compounds as flame retardants and tetraalkylpiperidine compounds as light stabilizers gives very unsatisfactory results in polyalkylenes, in particular polypropylene, and in ABS: The phosphorus compounds have a neutralizing effect on the light stabilizers, that is to say the light-protecting effect is reduced or is reduced completely canceled, in some cases the plastics even turn yellow. It was therefore surprising to find that the known negative effects of a combination of flame retardants and light stabilizers do not occur in methyl methacrylate polymers and copolymers.
Bevorzugte Stabilisatoren gegen die Lichtschädigung (Komponente a) sind die Verbindungen der Formeln I und II Preferred stabilizers against light damage (component a) are the compounds of the formulas I and II
worin die beiden R unabhängig voneinander Wasserstoff oder Methyl, die beiden Ri unabhängig voneinander Wasserstoff, Ci-18-Alkyl, Ci-i8-Alkoxy, Halogen, Hydroxy, Phenyl oder Phenoxy und die beiden R2 unabhängig voneinander Wasserstoff, Halogen, Hydroxy, Ci_i8-Alkyl oder Ci-is-Alkoxy, R10 Wasserstoff, Sauerstoff, Ci-e-Alkyl oder eine Gruppe der Formel -CO-R15, wherein the two R independently of one another are hydrogen or methyl, the two Ri independently of one another hydrogen, Ci-18-alkyl, Ci-i8-alkoxy, halogen, hydroxy, phenyl or phenoxy and the two R2 independently of one another hydrogen, halogen, hydroxy, Ci_i8- Alkyl or Ci-is-alkoxy, R10 hydrogen, oxygen, Ci-e-alkyl or a group of the formula -CO-R15,

Die Verbindungen der Formein I bis IV sind bekannt, bzw. lassen sich in Analogie zu bekannten Methoden zur Herstellung ähnlicher Verbindungen leicht herstellen. The compounds of forms I to IV are known or can be easily prepared analogously to known methods for the preparation of similar compounds.
Die erfindungsgemäss auszurüstenden Methylmethacrylat-Polymeren und -Copolymeren, üblicherweise unter dem Namen «Plexiglas» bekannt, werden ebenfalls nach allgemein bekannten Hersteilungsverfahren erhalten. The methyl methacrylate polymers and copolymers to be finished according to the invention, usually known under the name “Plexiglas”, are also obtained by generally known production processes.
Für die Copolymerisation werden z.B. die folgenden a, ß-ungesättigten Comonomere verwendet. Methacrylsäure-C2-8-aikylester, Acrylsäure-Ci-s-alkylester, a-Cyanacryisäure-Ci-s-alkylester (die Äthyl-, Butyl- oder Cyclohexylester sind bevorzugt), Styrol, Methylstyrol, Acrylnitril, Methacryinitrii oder a-Chloracrylnitril. For the copolymerization e.g. the following a, β-unsaturated comonomers used. C2-8 methacrylate, Ci-s-alkyl acrylate, Ci-s-alkyl a-cyanoacrylic acid (the ethyl, butyl or cyclohexyl esters are preferred), styrene, methyl styrene, acrylonitrile, methacrylonitrile or a-chloroacrylonitrile.
Bevorzugt verwendete Copolymere werden durch Polymerisation von Methylmethacrylaten in Gegenwart von Glycidylacrylat und/oder Glycidylmethacrylat, vorzugsweise in Gegenwart von Glycidylmeth-acrylat hergestellt. Vorzugsweise enthalten solche Copolymere 0,1 bis 10 Gewichtsprozent, insbesondere 0,5 bis 6 Gewichtsprozent (bezogen auf die gesamte Polymermasse) der entsprechenden Glycidylver-bindungen. im allgemeinen werden die Komponenten a und b (Lichtschutz- und Flammschutzmittel) den Monomeren oder Präpolymeren, bei Temperaturen zwischen etwa 20 und 150°C beigemischt, worauf die Polymerisation in Gegenwart eines Polymerisationskatalysators, z.B. Azo- bis -iso-butyronitril, Diben-zoylperoxid, Dilaurylperoxid oder tert-Butoxyperpivalat durchgeführt wird. Die Komponenten a und b können auch nach bekannten Methoden in die geschmolzenen Polymerisate und Copolymerisate eingearbeitet werden, z.B. im Extruder. Copolymers used with preference are prepared by polymerizing methyl methacrylates in the presence of glycidyl acrylate and / or glycidyl methacrylate, preferably in the presence of glycidyl methacrylate. Such copolymers preferably contain 0.1 to 10 percent by weight, in particular 0.5 to 6 percent by weight (based on the total polymer mass) of the corresponding glycidyl compounds. generally components a and b (light stabilizers and flame retardants) are added to the monomers or prepolymers at temperatures between about 20 and 150 ° C, whereupon the polymerization in the presence of a polymerization catalyst, e.g. Azo to isobutyronitrile, dibenzoyl peroxide, dilauryl peroxide or tert-butoxyperpivalate is carried out. Components a and b can also be incorporated into the molten polymers and copolymers by known methods, e.g. in the extruder.
Vorzugsweise arbeitet man zwischen 3 und 30%, insbesondere 8 bis 25% der Komponenten a und b, bezogen auf das Gewicht der Monomeren oder der Polymermassen ein. Wird ein Glycidylacrylat- oder Glycidylmethacrylat-enthaltendes Polymer stabilisiert, können geringere Mengen der Stabilisatoren verwendet werden, z.B. nur 3 bis 25%, vorzugsweise 8 bis 15% (bezogen wieder auf das Gewicht der Mono- oder Polymermassen). Dabei ist das Verhältnis der Komponenten a:b so zu wählen, dass in der Polymermasse schliesslich 0,01 bis 0,5, vorzugsweise 0,02 bis 0,2 Gewichtsprozente Lichtschutzmittel vorhanden sind, das heisst also, das Gewichtsverhältnis a:b ist etwa 3:97 bis 15:85. It is preferred to work in between 3 and 30%, in particular 8 to 25%, of components a and b, based on the weight of the monomers or of the polymer compositions. If a polymer containing glycidyl acrylate or glycidyl methacrylate is stabilized, smaller amounts of the stabilizers can be used, e.g. only 3 to 25%, preferably 8 to 15% (again based on the weight of the mono- or polymer masses). The ratio of components a: b is to be selected such that finally 0.01 to 0.5, preferably 0.02 to 0.2 percent by weight of light stabilizers is present in the polymer mass, that is to say that the weight ratio a: b is approximately 3:97 to 15:85.
