ABSTRACT OF THE DISCLOSURE A thermoplastic resin composition obtainable by blending 100 parts by weight of a mixture consisting of (A) 75 to 40% by weight of a propylene polymer, (B) 20 to 40% by weight of an ethylene-alpha- olefin copolymer, and (C) 5 to 30% by weight of a graft copolymer obtained by copolymerizing an aromatic vinyl compound and a polar vinyl compound in the presence of an ethylene-alpha-olefin copolymer with (D) 0.1 to 5 parts by weight of an unsaturated dicarboxylic acid, an anhydride thereof or a mixture of the two, and (E) 0.01 to 0.3 part by weight of an organic radical-generating agent, and then subjecting the resulting blend to thermal treatment. Said composition has not only a high bending modulus inherently possessed by polypropylene resins but also remarkably improved coating property. Accordingly, the composition is useful as interior and exterior trim parts of automobiles and exterior trim parts of motorcycles.
