A synthetic thermoplastic composition having excellent plate adhesion (of electroplated metal deposited on an electroless metal coating) is obtained by adding 0.5 to 5.0 parts by weight of a synthetic diene rubber to 100 parts thermoplastic graft copolymer produced by graft copolymerization of vinylic monomers onto a synthetic diene rubber. Typically a latex of the graft copolymer is blended with a latex of the synthetic diene rubber, the blend is coagulated, and the coagulum is dried. The uniform, intimate mixture of the latex blended polymers is formed in any suitable way into a molded body. When this molded plastic body is electroplated by conventional techniques involving forming an electroless coating of copper or nickel followed by electroplating, significantly enhanced plate adhesion is achieved.
