Patent ID: 7700692

Claim:
A process for preparing a polymer composite comprising the steps of A. forming a composition by combining 1. a polymer blend consisting essentially of a. a first polymer selected from the group consisting of polyethylenes and copolymers of ethylene and a C 3 -C 10 alpha-olefin; and b. a second polymer that is an ethylene vinyl alcohol polymer; wherein said polymer blend has a moisture content greater than 250 ppm water, based on the total weight of said first and second polymers; and 2. a third polymer that is a polar copolymer produced by a high pressure random copolymerization process, said polar copolymer comprising copolymerized units of ethylene and from about 3 wt. % to about 25 wt. %, based on the weight of the polar copolymer, of a comonomer selected from the group consisting of C 4 -C 8 unsaturated anhydrides, monoesters of C 4 -C 8 unsaturated acids having at least two carboxylic acid groups, diesters of C 4 -C 8 unsaturated acids having at least two carboxylic acid groups and mixtures thereof; wherein said composition consists essentially of, based on the total weight of said first, second and third polymers, 55-89 wt. % of said first polymer, 2-45 wt. % of said second polymer and 0.1-10 wt. % of said third polymer; B. subjecting said composition to high shear mixing to form a polymer composite that is a homogeneous blend; and C. recovering said polymer composite.
