Abstract
Abstract Acrylate monomers useful as a component of U.V. curable resin compositions and anaerobic adhesive compositions are provided and have the structure: ##STR1## where R a is an alkyl group containing up to about 18 carbon atoms, or an alkoxy ether moiety having the structure: ##STR2## where R c is an alkyl group containing up to about 18 carbon atoms, R c is hydrogen or a methyl group, and n is zero or a small integer, and R b has the structure: ##STR3## or ##STR4## where R e is hydrogen or an alkyl group and n' is a small integer.
