ABSTRACT:
Styrene based resin compositions comprise a styrene resin and a graft copolymer obtained by graft-polymerizing, in the presence of a butadiene based rubbery polymer, a monomer mixture composed of a monomer containing 1-50 ethylene oxide groups and one ethylenically-unsaturated bond and styrene or a monomer mixture compound of styrene as a principal component and at least one monomer copolymerizable with styrene. The a styrene based resin compositions are obtained by blending the graft copolymer with a styrene resin and having excellent impact strength and visual properties.
