Two oxime‐urethane derivatives, benzophenone oxime N ‐cyclohexylurethane (1 ) and dibenzophenone oxime N , N ′‐hexamethylenediurethane (2 ), were used as photobase generators. Photolysis of these derivatives results in the formation of amines which induce cross‐linking of poly(glycidyl methacrylate) (PGMA) upon heating. The bifunctional derivative 2 is more efficient than the monofunctional derivative 1 in inducing thermal cross‐linking of PGMA, with a maximum degree of insolubilization increasing up to ca. 90%.
