Abstract:
A composition of dental filling materials comprising a urethane oligomer obtained from a reaction between natural oil-derived polyols and a diisocyanate in excess to create terminals of isocyanate groups, the oligomer being grafted with an unsaturated acrylic monomer having hydroxyl groups which could react with the isocyanate terminals, and the resulting dental material being curable by free radical initiation.
