PURPOSE:To provide the title compsn. having excellent impact strength, rigidity, adhesion, weather resistance, gloss and moldability, consisting of a propylene polymer, a specified modified propylene polymer and a high-density ethylene polymer. CONSTITUTION:100pts.wt. propylene polymer or mixture (a) thereof with not more than 40wt% ethylene/propylene copolymer rubber is heat-treated in the presence of 0.1-50pts.wt. org. compd. (b) having at least one unsaturated bond per molecule [e.g., 2-hydroxyethyl(meth)acrylate] and 0.01-20pts.wt. org. peroxide (c) (e.g., dicumyl peroxide) to obtain a modified propylene polymer (B). Not less than 15wt% propylene polymer (A) having an MFR of 1.0-100g/10min is blended with 5.0-50wt% component B, 3-25wt% high-density ethylene polymer (C) having a density of not lower than 0.935g/cm<3> and an MFR of 0.1-100g/10 min and optionally, 2-40wt% powdered or flaky inorg. filler (D) having a particle size of not larger than 30mu in such a proportion that the content of the component (b) is 0.01-10wt%. |
