ADHESIVE POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an adhesive polymer composition excellent in molding processability and antiblocking properties and further heat resistance of adhesion and adhesive strength to a substrate. SOLUTION: This adhesive polymer composition comprises the following components (A) and (B). (A) 90-10 wt.% of a modified ethylene-α-olefin copolymer obtained by subjecting an ethylene-α-olefin copolymer having 0.870-0.930 g/cm3 density and an unsaturated carboxylic acid or its derivative to grafting reactional conditions and (B) 10-90 wt.% of a modified ethylene homopolymer or a modified ethylene-α-olefin copolymer prepared by subjecting 40-80 wt.% of an ethylene copolymer or an ethylene-α-olefin copolymer and 60-20 wt.% of an aromatic vinyl compound to grafting reactional conditions.
