Abstract:
(EN) The present invention addresses the problem of providing a novel thermoplastic resin composition for foam molding, which can produce a foam molded body having excellent heat resistance and foaming properties; and a foam molded body of the composition. Provided is a thermoplastic resin composition for foam molding, which contains 90-10 parts by mass of a methacrylic resin (A) and 10-90 parts by mass of a copolymer (B), wherein the copolymer (B) contains 45-85 mass% of styrene-based monomer units, 5-45 mass% of (meth)acrylic acid ester-based monomer units and 10-30 mass% of unsaturated dicarboxylic acid anhydride-based monomer units.
(FR) La présente invention aborde le problème de préparation d’une nouvelle composition de résine thermoplastique destinée au moulage de mousse, qui peut produire un corps moulé en mousse présentant d’excellentes propriétés de résistance à la chaleur et de formation de mousse ; et un corps moulé en mousse de la composition. La présente invention décrit une composition de résine thermoplastique destinée au moulage de mousse, qui contient de 90 à 10 parties en masse d’une résine méthacrylique (A) et de 10 à 90 parties en masse d’un copolymère (B), le copolymère (B) contenant de 45 à 85% en masse de motifs monomères à base de styrène, de 5 à 45 % en masse de motifs monomères à base d’ester (méth)acrylique et de 10 à 30 % en masse de motifs monomères à base d’anhydride d’acide dicarboxylique insaturé.
