ABSTRACT:
A dental filling material capable of forming a cured product with improved physical properties comprises a polymerizable monomer to be polymerized upon application, characterized in that the polymerizable monomer comprises a reaction product of two moles of a compound selected from the group consisting of hydroxyalkyl diacrylates and hydroxyalkyl dimethacrylates with on mole of an organic diisocyanate alone or in admixture with another polymerizable monomer. The reaction product may be bis(1,3-dimethacryloyloxy-2-propanetriyl)-N,N'-hexamethylene dicarbamate or bis(1,3-diacryloyloxy-2-propanetriyl)-N,N'-hexamethylene dicarbamate. The reaction product may be used in admixture with trimethylolpropane triacrylate and/or trimethacrylate and (mono-, di- or tri-)ethylene glycol diacrylate and/or dimethacrylate. The reaction product may also be used in admixture with bis-oxyethylenic bisphenol-A diacrylate and/or dimethacrylate and (mono-, di- or tri-)ethylene glycol diacrylate and/or dimethacrylate.
