Filed:

Dec 1, 2006

Appl. No.:

11/607424

Inventors:

Stephen O'Rourke - Bolingbrook IL, US

Assignee:

CPH INNOVATIONS CORP. - Chicago IL

International Classification:

B32B 27/00

US Classification:

428500000

Abstract:

Long chain esters formed by reacting mono, di-, and/or tri-carboxylic acids containing one, two, or three C-Clong chain radicals or fatty acid residues, and alcohols containing at least one C-Calkyl group, in a natural or synthetic vulcanizable or cross-linkable elastomer or rubber, when included with an adhesive resin, such as a melamine-containing resin or a phenol-, e.g., resorcinol-containing resin, e.g., a Novolak resin, unexpectedly increases the adhesion of one rubber or elastomer layer to another rubber or elastomer layer, even when the rubber/elastomer layers have substantially different polarities. Application of the adhesion promoters described herein is particularly contemplated for adhering one or more layers of difficulty adhered elastomers, such as fluorinated elastomers, to themselves, or to other elastomer layers that have similar or substantially different polarities.

Abstract:

The present disclosure is directed to plasticized elastomer compositions and methods of preparing plasticized elastomers. The plasticized elastomer compositions comprise an elastomer, and an unsaturated linear or branched dicarboxylic acid diester plasticizer. The compositions are formed by combining the elastic polymer and reactive ester plasticizer with a curing agent to react at least 5% by weight of the diester plasticizer to the elastic polymer. The elastomer includes natural and synthetic rubbers, such as nitrile butadiene rubber, hydrogenated nitrile butadiene rubber, chlorinated polyethylene rubber, and ethylene propylene diene monomer rubber. The plasticized elastomer compositions disclosed herein provide improved solvent immersion properties, and are useful, for example, for hoses, belts, conveyor belts, motor mounts, gaskets, automotive drive train belts, including transmission belts, roofing compounds, and the like.
