TRANSPARENT AND IMPACT-RESISTANT THERMOPLASTIC RESIN COMPOSITION

摘要

An impact-resistant thermoplastic resin composition improved in transparency, which comprises (A) 5 to 40 parts by weight of a graft copolymer produced by grafting at least one monomer selected from among alkyl methacrylates, aromatic vinyls, and vinyl cyanide onto enlarged rubber particles obtained by the aggregation and enlargement of a styrene/diene rubber latex by the use of a latex of a copolymer having acid groups which copolymer comprises an unsaturated acid, an aromatic vinyl, and an alkyl acrylate as the essential components and is controlled in refractive index and (B) 95 to 60 parts by weight of a copolymer obtained by polymerizing at least one monomer selected from among aromatic vinyls, alkyl methacrylates, and vinyl cyanide.
