Abstract
(EN)
Provided is a graft copolymer (B) obtained by graft polymerizing a vinyl-based monomer mixture (m1) containing an alkyl (meth)acrylate ester on to a copolymer (A) of an alkyl (meth)acrylate ester (Aa) and an aromatic hydrocarbon group-containing (meth)acrylic acid ester (Ab). Also provided are: a thermoplastic resin composition which contains a copolymer (C) obtained by polymerizing this graft copolymer (B) and a vinyl-based monomer mixture (m2) containing an alkyl (meth)acrylate ester; and a molded article of such composition. Also provided are: a graft copolymer that gives a thermoplastic resin composition having excellent transparency, impact resistance, weathering resistance and fluidity; a thermoplastic resin composition which contain this graft copolymer; and a molded article of such composition.

L'invention concerne un copolymère greffé (B) obtenu par polymérisation par greffage d'un mélange de monomères à base de vinyle (m1) contenant un ester d'alkyle (méth)acrylate sur un copolymère (A) d'un ester d'alkyle (méth)acrylate (Aa) et d'un ester d'acide (méth)acrylique contenant un groupe hydrocarboné aromatique (Ab). L'invention concerne également: une composition de résine thermoplastique qui contient un copolymère (C) obtenu par polymérisation de ce copolymère greffé (B) et un mélange de monomères à base de vinyle (m2) contenant un ester d'alkyle (méth)acrylate; et un article moulé à partir d'une telle composition. L'invention concerne également: un copolymère greffé qui donne une composition de résine thermoplastique ayant une excellente transparence, une excellente résistance aux chocs, une excellente résistance aux intempéries et une excellente fluidité; une composition de résine thermoplastique qui contient ce copolymère greffé; et un article moulé à partir de ladite composition.
