Abstract
Abstract Adhesive compositions having enhanced bond strength are obtained by mixing a monomeric ester of 2-cyanoacrylic acid with an anionic polymerization inhibitor and from 1 to 30 mmoles per kg. of adhesive of an adhesion promoter of the formula: ##STR1## wherein R' is hydrogen or an alkyl, aryl or cycloalkyl group having 1-10 carbon atoms. Such compositions may be used on a wide variety of substrates and are particularly useful on metals.
