摘要:
This invention relates to cyanoacrylate compositions that include, in addition to the cyanoacrylate component, a compound embraced by structure A: where D is independently a member selected from O or S, andA is independently a member selected from hydrogen, linear, branched or cyclic alkyl groups having from 1 to about 20 carbon atoms, alkenyl groups having from 2 to about 20 carbon atoms, alkynyl groups having from 2 to about 20 carbon atoms, and aryl groups having from 6 to about 20 carbon atoms, with or without interruption or substitution by a member selected from halogen, silicon, hydroxy, ester, and sulfate, provided that at least one A is not H and that at least one A has at least one carboxyl group attached thereto.
