Abstract:
A modified polyolefin resin composition, obtainable by graft modifying a mixed resin comprising(A) 40 to 99 parts by weight of a polyolefin; and (B) 1 to 60 parts by weight of an ethylenic compound-unsaturated carboxylic acid anhydride compound copolymer selected from the group consisting of an ethylene-maleic anhydride copolymer, an ethylene-propylene-maleic anhydride copolymer, an ethylene-propylene-butene-maleic anhydride copolymer, an ethylene-propylene-diene-maleic anhydride copolymer, a copolymer of ethylene and maleic anhydride with (meth)acrylic acid or (meth)acrylic ester, a copolymer of ethylene, propylene and maleic anhydride with (meth)acrylic acid or (meth)acrylic ester, a copolymer of ethylene, propylene, butene and maleic anhydride with (meth)acrylic acid or (meth)acrylic ester, a copolymer of ethylene, propylene, diene and maleic anhydride with (meth)acrylic acid or (meth)acrylic ester, and a mixture thereof; wherein (B) comprises 0.1 to 50% by weight of the unsaturated carboxylic acid anhydride compound; with an unsaturated carboxylic acid and/or its anhydride (C); wherein the modified polyolefin resin composition has a weight average molecular weight of 20,000 to 150,000 and a grafting weight of (C) of 0.1 to 20% by weight.
