PROBLEM TO BE SOLVED: To obtain the subject composition giving molded products safe on the contact of automobiles, etc., with human, having good coatability, blow- moldability, etc., and excellent in appearances by compounding high mol.wt. polytetrafluoroethylene to a resin composition comprising the graft copolymer of specific monomers to a rubbery elastomer and a copolymer comprising the monomers. SOLUTION: This composition which has a rubbery elastomer content of 25-55 wt.%, whose methyl ethyl ketone soluble content solution has a reducing viscosity of 0.4-0.8 dl/g, and whose molded product has a flexural strength of 200-500 kg/cm<2> , a falling weight strength of >=4 kg.m, a Rockwell hardness of 45-105 and a thermal deformation temperature of >=80 deg.C is obtained by compounding (A) 100 pts.wt. of a resin composition comprising (i) a graft copolymer of monomers such as an aromatic vinyl monomer, a vinyl cyanide monomer, etc., to a rubbery elastomer and (ii) the copolymer of he above monomers, with (B) 0.01-10 pts.wt. of polytetrafluoroethylene having a mol.wt. of 500,000-20,000,000. |
