A polyolefin product is produced by reacting a polyolefin grafted with a carboxylic acid or anhydride thereof with a polar polymer containing amino groups. The amino groups in the reaction products improves adhesion and compatibility properties.

Production of polyolefin copolymer

A polyolefin product is produced by reacting a polyolefin grafted with a carboxylic acid or an anhydride thereof with a polar polymer containing epoxy groups. The unreacted epoxy groups in the resulting copolymer improves adhesion and compatibility with metals and other resins.

This invention relates to a polyolefin composition with an improved weather resistance, which comprises a polyolefin blended with (1) a benzotriazole compound, (2) a heterocyclic hindered amine compound and (3) a phenyl benzoate compound or nickel complex compound.

Weather resistant polyolefin composition

The adhesive resin composition and laminate disclosed herein comprises a mixture of linear low density polyethylene, and a synthetic rubber reacted with an unsaturated carboxylic acid or derivative thereof.

Adhesive resin composition and laminate thereof

A linear low density polyethylene (a copolymer of ethylene and alpha-olefin) reacted with a carboxylic acid is disclosed. Laminates and compositions employing the modified polyethylene and/or synthetic rubber are also disclosed.

Modified polyethylene and laminate thereof

An improved polyethylene composition is disclosed. The composition comprises linear low density polyethylene (an ethylene/alpha-olefin copolymer) and a synthetic rubber. In one embodiment the composition includes a synthetic rubber reacted with a carboxylic acid.

Polyethylene composition comprising lldpe and rubber

An improved molding compound comprising a polyolefin modified with an unsaturated carboxylic acid, and has dispersed therein a filler material comprising a mixture of glass fiber and calcium silicate. In one embodiment the molding compound also includes an ethylene-.alpha.-olefin copolymer rubber.
