Reactive esters of 2-cyanopenta-2,4-dienoic acid and the adhesives and polymers thereof

Abstract

The present invention provides pure, storage stable, reactive esters of 2-cyanopenta-2,4-dienoic acid and the adhesives and polymers thereof. The monomers of the present invention have the formula: where R is alkyl, alkenyl, alkynyl, alkoxyalkyl, alkenyloxyalkyl, alkynyloxyalkyl, poly(oxyalkyl), aryl, cycloalkyl or a heterocyclyc radical. R may also be one of the foregoing moieties substituted with one or more of the other moieties; this includes the case of the substituent itself being substituted, and may also contain halogens. The reactive monomers of the present invention can be formulated into adhesives by incorporating certain modifiers and additives such as polymeric thickeners, viscocity regulators, plasticizers, thixotrophic agents, compatibilizers, adhesion promoters, pigments and colorants, fillers, deodorants and perfumes. They can also be used in composition with other monomers containing a reactive double bond such as for example cyanoacrylates.
