Abstract

Polymers comprising a polymer backbone having pendant or terminal betadiketone groups which contain at least one trifluoromethyl group. The betadiketone groups may be selected from trifluorocetoacetate groups (general formula I); ##STR1## hexafluoroacetylacetone groups (general formula II); ##STR2## or trifluoro-2,4-pentanedione groups (general formula III); ##STR3## where indicates the polymer backbone, R is an alkyl, substituted alkyl, aryl or substituted aryl group and R.sup.1 is hydrogen, alkyl or substituted alkyl. Neither the R group nor the R.sup.1 group should contain any group which is sufficiently basic to initiate cyanoacrylate polymerization or any group sufficiently acidic to interfere with chain transfer.
