<p>PURPOSE:To provide an olefin polymer composition composed of a crystalline propylene polymer, a styrene polymer, an ethylene-vinyl acetate copolymer, an ethylene polymer and an ethylene-propylene copolymer rubber and having extremely excellent paintability, printability and adhesivity. CONSTITUTION:The objective composition is obtained by compounding (A) 100pts.wt. of a crystalline propylene polymer having a melt index of 0.01-100g/ 10min with (B) 0.5-20.0pts.wt. of a styrene polymer composed mainly of styrene and having a molecular weight of 22,000-400,000, (C) 3-28pts.wt. of an ethylene- vinyl acetate copolymer having a vinyl acetate content of 5-50(wt)% and/or an ethylene-acrylic acid copolymer having an acrylate-content of 5-40%, (D) 3- 30pts.wt. of an ethylene polymer having a density of 0.9-0.975g/cm<3> and a melt index of >=0.1g/10min, and (E) 2-25pts.wt. of an ethylene-propylene copolymer rubber having Mooney viscosity (ML1+4100 deg.C) of <=140 and a propylene content of 20-75%.</p> |
