Abstract: Disclosed are composite compositions and articles prepared from such composites. The composition comprises or is produced from cellulose material, thermoplastic polymer, and a compatibilizing agent which is the reaction product of polyvinyl butyral, having hydroxyl functionality, and a second polymer which comprises or is produced from polyvinyl butyral and a second polymer wherein the polyvinyl butyral comprises a hydroxyl functionality and the second polymer reacts with at least a portion of the hydroxyl functionality.

Abstract: The present invention relates to a polyvinylbutyral (PVB) composition that is useful for blending with other polymers. The PVB composition of the present invention can be stored and used at ambient temperature without the occurrence of blocking by the PVB.

Abstract: The present invention provides a multi-layer polymer composition having a polar outer layer and a non-polar second outer layer. The polar outer layer is preferably PVC and the non-polar outer layer, polypropylene. The adhesive tie layer is a unique blend of a copolyester elastomer, a non-polar polymer, and a copolymer that contains functional groups capable of reaction with the functional end groups of the copolyester elastomer and that is totally or partially miscible with the non-polar polymer in the second outer layer. The multi-layer polymer can be advantageously coextruded. The non-polar outer layer can comprise the bulk of a fabricated part, with only a thin layer of polar polymer, providing desired attributes of the polar polymer at a lower cost.

Abstract: Polymers containing ?-methylenelact(ones)(ams) such as ?-methylenebutyrolactones are useful in blends with other polymers. For examples such polymers which have reactive groups are toughened by mixing with a rubbery material which has complimentary reactive groups, or polymers containing repeat units derived from ?-methylenelact(ones)(ams) are toughened by mixing with polymeric core-shell particles having an elastomeric core and a specified thermoplastic shell. The properties of thermoplastics are also improved by blending with ?-methylenelact(ones)(ams) such as ?-methylenebutyrolactones containing (co)polymers.

Abstract: A process for reducing the carbonyl group of a polyketone consisting of a carbon monoxide ethylene-based copolymer, comprising reacting a blend of carbon monoxide ethylene-based polymer with a metal alkoxide in a molten condition in proportions to provide a novel polyalcohol. This chemical modification changes the properties of the carbon monoxide ethylene-based polymers and renders them eligible for uses for which the original polymers were not or not very suitable.

Abstract: A novel composition is disclosed which comprises polyvinyl chloride, an ethylene-based copolymer as a compatibilizer, inorganic fillers and from about 5 to 95 percent by weight of either virgin or recycled/recovered polyvinyl butyral. A process for preparing this novel composition is also provided.

Abstract: A novel plasticizer composition is disclosed which comprises an ethylene copolymer combined with a reactive ultraviolet (UV) absorbing agent by reaction. Useful UV absorbing agents include homopolymers and copolymers of vinyl-functionalized monomer of benzotriazole, benzophenone, or benzophenolate. A process for preparing this novel plasticizer composition is also provided.

Abstract: Halide polymers such as polyvinyl chloride and polyamides melt blended at a polyamide to halide polymer weight ratio of about 1.5:1 to about 2:1 with an effective amount of a carboxyl and/or CO-functional ethylene polymer to compatibilize the halide polymer and polyamide exhibit superior chemical resistance.
