ABSTRACT:
Homopolymers and copolymers of glycidyl esters are made by reacting the acids to be esterified with the corresponding polymer of tert.-alkyl glycidyl ether under substantially anhydrous conditions and in the presence of a strong acid catalyst, preferably a sulfonic acid. The reaction proceeds satisfactorily at about 100.degree.14 150.degree. C with displacement of the tert.-alkyl group by the acyl group of the acid and evolution of tert.-olefin. By use of the appropriate proportion of reactant acid and/or appropriate reaction time, any desired proportion of the glycidyl groups can be esterified.
