ABSTRACT:
A resin composition which includes (A) 100 parts of a blend of a polyacrylate and a poly(alkylene-phenylene ester) and (B) 1-50 parts of a chemically modified polyolefin copolymer exhibits superior impact resistance, particularly low temperature impact resistance, while retaining good melt viscosity for molding. The polyacrylate may be produced by polymerizing a dihydric phenol formula I: ##STR1## with an aromatic dicarboxylic acid, a dichloride derivative, an alkylated derivative or an arylated derivative thereof. The chemically modified polyolefin copolymer has a structural unit containing at least one amide group at and at least one glycidyloxy or glycidyl group, with the number of the structural unit contained in the copolymer being one per from 4 to 5,000 carbon atoms of the polyolefin moiety.
