Keyword(s) conversion hydrophobicity polymerization shrinkage synthesis urethane methacrylates viscosity Abstract/Summary In this study, we have reacted Bis-GMA with mono-functional alkyl isocyanates (RNCO) of varying chain length. The resulting urethane group is known to form weaker hydrogen bonds compared to the hydroxyl group but is expected to have higher cohesive energy density than ester or ether linkages. These urethane derivatives of Bis-GMA are expected to have much lower viscosities and water uptake than Bis-GMA and exhibit higher conversion of vinyl groups without excessively increasing polymerization shrinkage of dental resin systems.
