Abstract
Abstract A thermoplastic resin composition comprising (1) a graft copolymer (GP) prepared by graft-copolymerizing at least one ethylenically unsaturated monomer (C) with a substratum polymer (AB) having pendant double bonds prepared from at least one comonomer (A) expressed by the general formula wherein X is a hydrogen atom, an alkyl group containing 1 to 18 carbon atoms, a hydroxyethyl group, a hydroxypropyl group or an aminoethyl group, AND AT LEAST ONE OTHER ETHYLENICALLY UNSATURATED MONOMER (B), and (2) at least one thermoplastic polymer or copolymer (TP).
