Abstract
Abstract Adhesive resins obtained by reacting 100 parts by weight of an epoxy group-containing olefin polymer with 0.01-10 parts by weight of at least one ethylenically unsaturated fatty acid or derivative thereof, are described. The adhesive resins or olefin polymer compositions comprising the adhesive resins are particularly useful in lamination with other types of resins. Such laminates are also described.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
An adhesive resin obtained by chemically combining, in the presence of a radical initiator 0.01-10 parts by weight of at least one ethylenically unsaturated fatty acid or anhydride thereof with 100 parts by weight of an epoxy group-containing olefin polymer prepared by subjecting 50-99 wt. % of ethylene, 0.05-50 wt. % of at least one unsaturated glycidyl group-containing monomer and up to 49.95 wt. % of at least one other ethylenically unsaturated monomer, to high pressure polymerization.
Claim 2
Dependent Claim
77 words
An adhesive resin obtained by chemically combining, in the presence of a radical initiator 0.01-10 parts by weight of at least one ethylenically unsaturated fatty acid or anhydride thereof with 100 parts by weight of an epoxy group-containing olefin polymer prepared by subjecting 50-99 wt. % of ethylene, 0.05-50 wt. % of at least one unsaturated glycidyl group-containing monomer and up to 49.95 wt. % of at least one other ethylenically unsaturated monomer, to high pressure polymerization.
