Abstract
There is provided a thermoplastic resin composition and interior or exterior parts for vehicle using thereof, which is excellent in flexibility, surface appearance, heat deformation property at heating and has low tackiness at a high temperature. The thermoplastic resin composition comprises 25 to 90 parts by weight of a (meth)acrylic ester copolymer (X), which is prepared by polymerizing 40 to 95% by weight of a (meth)acrylic ester, 0 to 40% by weight of a vinyl cyanide compound, not more than 60% by weight of an aromatic vinyl compound and 0 to 40% by weight of a monomer copolymerizable therewith, and has a glass transition temperature of not more than 20.degree. C. and a gel content of not more than 50% by weight, 5 to 75 parts by weight of a copolymer (Y), which has a glass transition temperature or a melting point not less than 50.degree. C., and 0 to 70 parts by weight of a graft copolymer (Z), which is prepared by polymerizing 5 to 95% by weight of a rubber polymer (A) and 5 to 95% by weight of a vinyl monomer (B), and wherein hardness thereof at 20.degree. C. measured by the method of JIS K6301 is 30 to 100.
