| titleOfInvention | Polymethacrylate moulding matters stabilised against discolouration at thermal stress |
| abstract | (m1) 50 - 98 Gew.-% Alkylmethacrylat mit 1 bis 6 Kohlenstoffatomen im Esterrest, (m2) 1 - 25 Gew.-% Vinylaromat, (m3) 1 - 25 Gew.-% Maleinsäureanhydrid, sowie gegebenenfallsn (m4) 0 - 5 Gew.-% Alkylrest mit 1 bis 6 Kohlenstoffatomen im Esterrest, wobei die Summe aus (m1), (m2), (m3) und gegebenenfalls (m4) 100 Gew.-% ausmacht, nenthaltend, bezogen auf 100 Gew.-Teile CP, 0,001 bis 2 Gew.-Teile einer organischen Phosphitverbindung OP, die mindestens einen sterisch gehinderten Phenoxysubstituenten aufweist, der über das Sauerstoffatom kovalent mit dem Phosphoratom verbunden ist. Vorzugsweise ist die organische Phosphitverbindung OP Tris(2,4-dialkylphenyl)phosphit oder Bis(2,4,6-trialkylphenyl)pentaerythritoldiphosphit. Weiterhin bevorzugt sind das Monomere (m1) Methylmethacrylat und das Monomere (m2) Styrol und/oder α-Methylstyrol.The invention relates to a polymethacrylate molding compound FM, consisting of a copolymer CP, composed of: (m1) 50-98% by weight Alkyl methacrylate with 1 to 6 carbon atoms in the ester radical, (m2) 1 - 25% by weight Vinyl aromatic, (m3) 1 - 25% by weight Maleic anhydride, and if necessary (m4) 0 - 5% by weight Alkyl radical with 1 to 6 carbon atoms in the ester radical, the sum of (m1), (m2), (m3) and possibly (m4) making up 100% by weight, containing, based on 100 parts by weight of CP, 0.001 to 2 parts by weight of an organic phosphite compound OP which has at least one sterically hindered phenoxy substituent which is covalently linked to the phosphorus atom via the oxygen atom. The organic phosphite compound OP is preferably tris (2,4-dialkylphenyl) phosphite or bis (2,4,6-trialkylphenyl) pentaerythritol diphosphite. Also preferred are the monomer (m1) methyl methacrylate and the monomer (m2) styrene and / or α-methylstyrene. |
