Preparation and Characterization of Dimer Fatty Acids-Based Vinyl Ester Resin Monomer
Novel dimer fatty acids-based vinyl ester resin monomer was prepared via simple ring-opening and esterification reaction with the aid of dimer fatty acids (DA) and glycidyl methacrylate (GMA) as raw material. The effects of different catalyst system, reacting time and reacting temperature on the yield, color, and viscosity of the final product were analyzed. The results of optimal experiments showed that BTEAC catalyst could make the final product with moderate viscosity and lighter color, the optimal BTEAC catalyst addition amount was 0.5wt.%, the optimal reacting temperature and reacting time was 115 °C and 2h, respectively. FTIR and 13C-NMR demonstrated that the target product had been successfully synthesized.
