Abstract:
(EN) A thermoplastic resin composition of the present invention comprises a rubber-modified vinyl-based graft copolymer, a first aromatic vinyl-based copolymer, a second aromatic vinyl-based copolymer, and a polyalkylene glycol, wherein the first aromatic vinyl-based copolymer is a copolymer of methyl methacrylate, methyl acrylate, an aromatic vinyl-based monomer, and a monomer copolymerizable with the aromatic vinyl-based monomer, the second aromatic vinyl-based copolymer is a copolymer of an aromatic vinyl-based monomer and a monomer copolymerizable with the aromatic vinyl-based monomer, and the weight ratio of methyl methacrylate and methyl acrylate, in the first aromatic vinyl-based copolymer, is approximately 1:0.01 to approximately 1:0.2. The thermoplastic resin composition has excellent discoloration resistance, color, transparency, and the like even after being irradiated with ionizing radiation.
(FR) La présente invention concerne une composition de résine thermoplastique comprenant un copolymère greffé à base de vinyle modifié par du caoutchouc, un premier copolymère à base de vinyle aromatique, un second copolymère à base de vinyle aromatique, et un polyalkylène glycol, le premier copolymère à base de vinyle aromatique étant un copolymère de méthacrylate de méthyle, d'acrylate de méthyle, d'un monomère à base de vinyle aromatique et d'un monomère copolymérisable avec le monomère à base de vinyle aromatique, le second copolymère à base de vinyle aromatique étant un copolymère d'un monomère à base de vinyle aromatique et d'un monomère copolymérisable avec le monomère à base de vinyle aromatique, et le rapport en poids du méthacrylate de méthyle et de l'acrylate de méthyle, dans le premier copolymère à base de vinyle aromatique, est d'environ 1:0,01 à environ 1:0,2. La composition de résine thermoplastique présente une excellente résistance à la décoloration, une belle couleur, une excellente transparence et similaires même après avoir été exposée à un rayonnement ionisant.
