PURPOSE:To provide a polymer compsn. which has excellent heat resistance, flexibility and adhesion to coating films and gives moldings for exterior finish materials for automobile which an be coated and baked, consisting of two ethylene/vinyl acetate copolymers having different vinyl acetate contents and PE and/or an ethylene/alpha-olefin copolymer. CONSTITUTION:50-85% (by weight; the same applies hereinbelow) ethylene/vinyl acetate copolymer (A) having a vinyl acetate content of 3-15% is dry-blended or melt-blended with 5-40% ethylene/vinyl acetate copolymer (B) having a vinyl acetate content of 25-45%, 5-25% PE such as a medium-density PE having a density of 0.930g/cm<3> or above, a high-density PE or a linear low- density PE having a density of lower than 0.930g/cm<3>, etc. and/or ethylene/alpha- olefin copolymer (C) and optionally, a filler, colorant, an antioxidant, a weathering stabilizer, etc., (D) to obtain a polymer compsn. having a vinyl acetate content of 8-15%. |
