ABSTRACT:
A multiply grafted copolymer is obtained by graft-polymerizing onto non-elastic trunk polymer particles (a) a monomer mixture (b) comprising an elasticity-imparting monomer selected from conjugated dienes and acrylates, a polyalkylene oxide monomer comprising 4 to 500 alkylene oxide groups together with a terminal double bond and an optional ethylenically unsaturated monomer, and an ethylenically unsaturated monomer (c) in order. An antistatic resin composition comprising this multiply grafted copolymer alone or a mixture of this copolymer and a thermoplastic resin compatible therewith can utilize the rubbery polymer component (b) more effectively than an antistatic resin composition comprising a graft copolymer obtained by graft-polymerizing an ethylenically unsaturated monomer (c) onto a trunk polymer comprising a mere copolymer of a monomer mixture (b), and thus can provide an improved antistatic effect.
