Abstract
Abstract Adhesive resins obtained by reacting 100 parts by weight of an epoxy-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.

Claim 1
Independent Claim
120 words
A laminate article comprising at least two layers formed by laminating at least one substrate material with a member selected from an adhesive resin and an olefinic polymer composition containing the same, the adhesive resin forming a layer in the resulting laminate article and being 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 derivative thereof with 100 parts by weight of an epoxy group-containing olefin polymer prepared by subjecting 50-99.95 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 radical polymerization.
Claim 2
Dependent Claim
120 words
A laminate article comprising at least two layers formed by laminating at least one substrate material with a member selected from an adhesive resin and an olefinic polymer composition containing the same, the adhesive resin forming a layer in the resulting laminate article and being 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 derivative thereof with 100 parts by weight of an epoxy group-containing olefin polymer prepared by subjecting 50-99.95 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 radical polymerization.
