Process for recycling polyolefin blend composition using an ethylene copolymer compatibilizing agent

A process for preparing a shaped article from a composite material which comprises the steps of

• A. preparing a composite material by a process comprising the steps of
• 1. forming a composition by combining
• a. a polymer blend comprising
• (1) a first polymer selected from the group consisting of polyethylenes and copolymers of ethylene and a C3-C10 alpha-olefin;
• and
• (2) a second polymer selected from the group consisting of ethylene vinyl alcohol polymers and mixtures of two or more thereof;
• 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
• b. 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 C4-C8 unsaturated anhydrides, monoesters of C4-C8 unsaturated acids having at least two carboxylic acid groups, diesters of C4-C8 unsaturated acids having at least two carboxylic acid groups and mixtures thereof;
• wherein said composition comprises, based on the total weight of said first, second and third polymers, 55-98 wt. % of said first polymer, 2-45 wt. % of said second polymer and 0.1-10 wt. % of said third polymer;
• and
• 2. subjecting said composition to high shear mixing to form a homogeneous composite material;
• and
• B. forming said composite material into a shaped article.
