There is disclosed a process for conveniently preparing polymers having pendant ultraviolet polymerizable groups of the acrylate or methacrylate types, which process involves co-reacting a polymer containing the C-X moiety with a monomer having the general formula [Figure] wherein X is OH or COOH and Y is OH when X is OH, and OR′OH when X is COOH, wherein R′is C1-C6 alkyl. This process is catalyzed utilizing an essentially solid ion exchange catalyst.
