摘要

Disclosed is a thermoplastic resin composition comprising a graft polymer resin (I) obtained by polymerizing one or more monomers (b) selected from the group consisting of aromatic vinyl compounds and ethylenically unsaturated compounds, in the presence of a latex of an ethylene-propylene-non-conjugated diene terpolymer rubber (a) having a specific gel content and a specific particle diameter, so that the graft polymer resin contains a specific proportion of the rubber (a); and a rigid thermoplastic resin (II). This resin composition has excellent weather resistance and impact resistance, and yields molded articles having a good surface gloss.
