THERMOPLASTIC RESIN COMPOSITION

摘要

There is disclosed a thermoplastic resin composition comprising a blend of 100 parts by weight of a resin composition composed of 1 to 99% by weight of a polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto polypropylene, and a composition composed of the modified polypropylene (A) and a polypropylene (B), and 99 to 1% by weight of at least one saturated polyester resin (D), 0.1 to 300 parts by weight of an epoxy group containing copolymer (E), 0.1 to 300 parts by weight of a modified ethylenic copolymer rubber (F) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto ethylenic copolymer rubber, and up to 5 parts by weight of a basic compound (G) optionally added as reaction accelerator, the content of the saturated polyester resin in the thermoplastic polyester resin being less than 50% by weight. The thermoplastic resin composition of the present invention has high heat resistance and high impact resistance, in particular, high low-temperature impact resistance and is advantageously used in automobile parts, electric and electronic parts.
