Abstract: PURPOSE:To obtain a thermoplastic resin compsn. having excellent rigidity and impact resistance with improvements in the tensile toughness and chemical resistance of a thermoplastic styrene resin by blending the thermoplastic styrene resin with a modified polyolefin resin and a specific modified graft copolymer. CONSTITUTION:A thermoplastic resin compsn. comprises the following components [A] to [C]. The component [A] is a thermoplastic styrene resin. The component [B] is a modified polyolefin resin prepd. by grafting a polyolefin resin with an alpha,beta-unsatd. carboxylic acid or a deriv. thereof, the amt. of which is 0.1 to 15wt.%, based on the polyolefin resin. The component [C] is either a modified graft copolymer prepd. by graft copolymn. of a diene rubber with a monomer mixture of an oxazolyl group-contg. vinyl monomer and other copolymerizable monomer, or a modified graft copolymer compsn. comprising the above-mentioned modified graft copolymer and a copolymer of the remaining monomers. The blending ratio is such that [A]/[B]=-5/95 to 95/5 (wt. ratio) and the amt. of the component [C] is l-100 pts.wt. per 100 pts.wt. in total of the components [A] and [B].

Abstract: PURPOSE:To obtain a thermoplastic resin composition having good compatibility among components and excellent in impact resistance, tensile toughness, and rigidity by mixing a thermoplastic styrene resin with a modified polyolefin resin and a modified vinyl polymer having oxazolyl groups. CONSTITUTION:This composition comprises a thermoplastic styrene resin (A) (e.g. a rubber-reinforced styrene-resin), a modified polyolefin resin (B) obtained by grafting an alpha,beta-unsaturated carboxylic acid or a derivative thereof onto a polyolefin resin (b) (e.g. an ethylene/alpha-olefin copolymer rubber) in an amount of 0.1-15wt.% based on the resin (b), and a modified vinyl polymer (C) having oxazolyl groups, wherein the (A) to (B) ratio is 5/95 to 95/5 by weight and the amount of (C) is 1-100 pts.wt. per 100 pts.wt. the sum of (A) and (B). The component (C) is a copolymer of a vinyl monomer having an oxazolyl group (e.g. 2-propenyl-2-oxazoline with a copolymerizable vinyl monomer (e.g., acrylonitrile).
