    The purpose of this work was to obtain a polymeric material aimed at being easily applied in a thin film on an organic substrate for dental applications. A maleic anhydride copolymer functionalized with a urethane derivative bearing methacrylate groups was synthesized, and by its mixing with commercial dental monomers, two light-curing formulations were prepared and investigated. The surface morphology and physicochemical properties of the obtained materials are affected by their composition. An increase of the diffusion coefficient from 0.38 at 3.58 mu m(2)/s (estimated by fluorescence recovery after photobleaching) could ensure minimal moisture of an organic injectable paste situated under this polymer film.
