Hyperbranched multimethacrylate resins of low viscosity and low oxygen inhibition
for dental applications (in English)
Polimery 2010, No 4, 284
This work presents the syntheses and characterization of new low viscosity and low oxygen inhibition hyperbranched multimethacrylate macromonomers capable of photopolymerization, for application in dental composites. Two types of multimethacrylate resins were synthesized. One based on bisphenol A core and polyether branches and the other one based on trimethylolpropane (TMP) and polyether structure containing urethane bonds, obtained with isocyanate or non-isocyanate method. The monomers were characterized by spectroscopic methods. The conversion of double bonds was investigated by FTIR. The physical properties of the multimethacrylate resins such as viscosity, density and polymerization shrinkage were determined. Based on the results obtained it has been shown that such resins are attractive materials to use in composites, especially dental ones.
