Abstract
Several novel dimethacrylates have been developed as alternative matrix materials for dental composite applications. For the cured bulk polymers the equilibrium water uptake, reduction of glass transition temperatures (Tgs) by water sorption, refractive indices and the surface hardness have been determined. The properties were then compared with those of the control Bis-GMA. These properties correlated well with the structures of the polymers. Polar groups were found to increase the water sorption and thus reduce surface hardness.
