Abstract:
A modified polyolefin composition having a weight average molecular weight of not less than 30,000 to not more than 150,000, obtained by graft polymerizing 0.5 to 15.0% (by weight) of (B) maleic anhydride and 0.1 to 7.5% (by weight) of (C) styrenic monomer to (A) polypropylene, ethylene-propylene copolymer, wherein a propylene content of said ethylene-propylene copolymer is over 85% (by weight), or ethylene-propylene-butene copolymer, wherein a propylene content of said ethylene-propylene-butene copolymer is not less than 50% (by weight), the grafting weight ratio (B/C) of (B) to (C) being not less than 2 to not more than 5.
