Abstract
An acetoacetate moiety may be introduced into polymers and used via Michael Reaction for crosslinking with alpha, beta-unsaturated esters.
Claims9
A method for effecting the crosslinking of polymers comprising the steps of introducing into an acrylate polymer backbone a plurality of pendant acetoacetate moieties, mixing said polymer with a crosslinking quantity of at least one polyacrylate having at least two groups of the structure ##STR4## pendantly attached to an organic radical selected from the group consisting of alkyl, aryl, alkyl-aryl and polymeric radicals, and with a strong base catalyst effective to initiate a Michael Reaction and effecting reaction between said pendant acetoacetate moieties and said polyacrylate.
