ABSTRACT:
A resin composition containing a mixture of a polycarbonate resin and a rubber-reinforced styrene base resin which is prepared by polymerizing, in the presence of a rubbery polymer, a monomer mixture of an aromatic vinyl monomer, at least one of cyanated vinyl monomers and alkyl esters of unsaturated carboxylic acids and at least one other vinyl monomer; a polyolefin graft polymer which is prepared by polymerizing, in the presence of a crystalline polyolefin, a monomer of an aromatic vinyl monomer and at least one of cyanated vinyl monomers and alkyl esters of unsaturated carboxylic acids; and optionally a terpolymer of an olefin, an unsaturated dicarboxylic anhydride and an alkyl ester of an unsaturated carboxylic acid or an epoxy group-containing olefin copolymer of an unsaturated epoxy compound, an olefin and optionally an ethylenically unsaturated compound, which composition has good coating properties.
