摘要:
Disclosed is a graft copolymer resin prepared by graft polymerizing a vinyl compound onto a composite-structured acrylic rubber whose particles are composed of a core consisting of a diene rubber enlarged by treatment with an acid group-containing copolymer latex, and an outer layer consisting of an acrylate polymer having a crosslinked structure formed by the combined use of a graft-linking agent and a cross-linking agent. This graft copolymer resin may be blended with a rigid thermoplastic resin in a specific proportion. This resin composition imparts a good gloss to the molded articles formed therefrom, while retaining excellent impact resistance and weather resistance.
