Abstract
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 ##STR1## wherein X is OH or COOH and Y is OH when X is OH, and OR'OH when X is COOH, wherein R' is C.sub.1 -C.sub.6 alkyl. This process is catalyzed utilizing an essentially solid ion exchange catalyst.
