Abstract

PURPOSE:To obtain the title composition excellent in the balance between rigidity and impact resistance, by mixing a crystalline ethylene/propylene block copolymer with a specified crosslinked copolymer. CONSTITUTION:An ethylenically unsaturated silane compound of the formula (wherein R is an ethylenically unsaturated hydrocarbon group or a hydrocarbonoxy, R' is an aliphatic hydrocarbon group, R'' is a hydrolyzable organic group and n is 0-2) is grafted onto a crystalline ethylene/propylene block copolymer in the presence of an organic peroxide, and the product is brought into contact with water at room temperature to 100 deg.C for 1-24hr in the presence of a silanol condensation catalyst (e.g., dibutyltin dilaurate) to obtain a crosslinked copolymer (B). 5-40wt.% crystalline ethylene/propylene block copolymer (A) of an intrinsic viscosity of 1-4dl/g and a crystallinity of 30-60% is mixed with 1-50pts.wt. component B.
