PURPOSE:To provide a composition composed of a crystalline propylene polymer, an ethylene-vinyl acetate copolymer, a modified propylene polymer and, as necessary, a filler and having excellent mechanical strength, moldability, appearance of molded article and adhesivity with adhesive. CONSTITUTION:The objective composition is composed of (A) a crystalline propylene polymer having an MFI of 0.01-100g/10min, preferably 0.01-80g/10min, (B) an ethylene-vinyl acetate copolymer having a vinyl acetate content of 5-50wt.%, (C) a modified propylene polymer produced by the heat- treatment of 0.01-10pts.wt. of an organic compound having >=1 unsaturated bond and OH in one molecule and 0.01-10pts.wt. of an organic peroxide and, as necessary, (D) a filler. The amounts of the components A, B and C are >=40wt.%, 5-30wt.% and 5-40wt.% based on A+B+C, respectively and the amount of the component D is <=40pts.wt. per 100pts.wt. of A+B+C. The composition contains 2.5-10wt.% of the unit originated from vinyl acetate. |
