Abstract
A thermoplastic resin composition is described, comprising (a) a polyphenylene ether resin, (b) a polar thermoplastic resin having a polar functional group, and (c) a modified block copolymer obtained by subjecting a hydrogenated block copolymer comprising an aromatic vinyl compound polymer block (A) and a conjugated diene compound polymer block (B) to graft polymerization in the presence of a monomer having an epoxy group. The resin composition is excellent in impact resistance, solvent resistance, and compatibility among the resinous components thereof.
