Adhesion compositions for multilayer structures

摘要

The present invention relates to bonding resins having excellent adhesion to polar polymers, particularly ionomers, acid copolymers and ethylene vinyl alcohol copolymer. These resins preferably contain: 1) an ethylene polymer or copolymer (ungrafted, grafted or partially grafted); 2) a grafted elastomer; and 3) optionally, an ethylene alpha olefin copolymer which is wholly or partially grafted. Preferred grafting comonomers include maleic anhydride and derivatives thereof.
