Modified polyolefin-polyester graft copolymer, method of producing same and thermoplastic resin composition containing such graft copolymer

摘要

A modified polyolefin-polyester graft copolymer includes (a) 10-90 parts by weight of a polyester having an intrinsic viscosity [&eegr; ] of 0. 30-1.20 and an end carboxyl group content of 15-200 milliequivalent/kg, and (b) 90-10 parts by weight of a modified polyolefin having 0.2-5 mol % of an epoxy group or carboxyl group content and a weight-average molecular weight of 8,000-140,000.PP A thermoplastic resin composition includes (a) 5-95 weight % of an aromatic polycarbonate, (b) 95-5 weight % of a polyolefin, and (c) 1-30 parts by weight, per 100 parts by weight of (a)+(b), of the graft copolymer.
