ABSTRACT:
A graft copolymer is obtained by graft-polmerizing a vinyl or vinylidene monomer onto a rubber trunk polymer which comprises a polyalkylene oxide monomer comprising 4 to 500 alkylene oxide groups together with an ethylenic unsaturation, and a conjugated diene and/or an alkyl acrylate.
This graft copolymer alone or in a mixture thereof with another thermoplastic resin, because of the presence of the polyalkylene oxide monomer unit incorporated in the rubber trunk polymer, provides a resin composition possessing excellent antistatic property, which, practically, is not lowered by washing.
