ABSTRACT:
A graft copolymer is obtained by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer which is a copolymer of 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. By adding an anionic surfactant to a base resin which comprises this graft copolymer alone or a mixture of this graft copolymer and another thermoplastic resin, an antistatic resin composition can be obtained. The resin composition thus obtained possesses excellent and permanent antistatic property that is not lowered by washing or wiping as is the case with conventional antistatic resins comprising an antistatic agent.
