EXTRUDABLE BONDING RESIN COMPOSITION COMPRISING AT LEAST TWO DIFFERENT ETHYLENE COPOLYMERS HAVING AT LEAST ONE COMONOMER IN COMMON, AND A TACKIFYING RESIN; LAMINATES HAVING THESE COMPOSITIONS AS BONDING AGENT

摘要

An extrudable bonding resin composition of (a) 65 to 99 percent of an ethylene copolymer portion of a copolymer of ethylene and 20 to 50 percent comonomer of acids, esters, and the like, and grafted sidechains of comonomer units selected from carboxylic acid, anhydride, salt, or half ester functionality, and optionally a compatible non-grafted ethylene copolymer, and (b) 1 to 35 percent by weight of a tackifying resin exhibits good adhesion properties without the need for a primer.
