A resin composition for bumpers including:

Resin composition for bumpers

Modified polymer compositions comprising elastomers blended with not more than 50 parts by weight of a crystalline polyolefin are prepared by reaction of the polymers with an unsaturated carboxylic acid or its acid anhydride. The modified composition optionally containing a filler, is particularly suitable for laminating to metals and other polymers; laminates show superior hot water resistance, salt water resistance and thermal shock resistance.

Modified elastomer and laminate thereof

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.

Production of polyolefin copolymer

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

A polyolefin composition comprising a modified polyolefin obtained by adding an unsaturated carboxylic acid or an anhydride thereof to a polyolefin or mixtures of said modified polyolefin and an unmodified polyolefin, an inorganic filler, one or more nucleating agents or a combination thereof with one or more heat deterioration inhibitors, said polyolefin composition evidencing reduced deterioration by heat or reduction of its mechanical strength during a molding operation.

Polyolefin composition containing (a) filler (b) nucleating agent and

A process for the production of modified polyolefins by combining a polyolefin with one or more carboxylic acids or their anhydrides in the presence of a radical producing agent in an extruder and in the presence of an organosilane. If desired glass fibers can also be incorporated at the same time.
