Grafted polyolefin composition having improved adhesiveness

摘要

A composition having improved adhesion to polar solid materials which comprises (A) 99 to 70 parts by weight of a modified crystalline polyolefin having grafted thereto a monomer selected from the group consisting of unsaturated carboxylic acids and their anhydrides, esters, amides imides and metal salts, said crystalline polyolefin having a degree of crystallinity measured by an X-ray analysis, of at least 25% and containing the grafting monomer in an amount of 0.0001 to 3% by weight based on the total amount of the crystalline polyolefin and the grafting monomer; and (B) 1 to 30 parts by weight of a hydrocarbon elastomer.
