THERMOPLASTIC RESIN COMPOSITION

PURPOSE:To obtain a thermoplastic resin composition having excellent chemical resistance and impact resistance by blending a saturated polyester resin with rubber reinforced styrene-based resin and a specific epoxy modified copolymer in a specific ratio. CONSTITUTION:(A) A saturated polyester resin is blended with (B) a rubber- reinforced styrene-based resin prepared by copolymerizing B1: 50-90wt.% aromatic vinyl-based monomer with B2: 10-50wt.% vinyl cyanide monomer and B3: 0-40wt.% another copolymerizable vinyl-based monomer, (C) an epoxy modified copolymer comprising 50-89.9wt.% B1, 10-49.9wt.% B2, 0-39.9wt.% B3 and C1: 0.1-20wt.% ethylene-based unsaturated epoxy group-containing monomer and (D) a styrene-based copolymer comprising 20-90wt.% B1, 10-50wt.% B2 and 0-70wt.% B3 in the ratio to give 90-10 pts.wt. A, 90-10 pts.wt. B+C and 0-80 pts.wt. C to give a composition comprising 5-40wt.% rubber-like polymer and >=0.001wt.% C1 in the composition.
