Preparation of Self Curable Unsaturated Polyester with Pendant Hydroxyl Groups and Investigation of its Curing Properties

Abstract:

Self curable unsaturated polyesters with pendant hydroxyl groups on main chain were synthesized through the polycondensation of maleic anhydride and glycidol at different raw material ratios. The preparation process and self-curing properties were studied. Investigation demonstrated that the unsaturated polyester resin could be self cured through the addition reaction of pendant hydroxyl groups with the double bonds on main chain when it was heated above 150°C without additional cross-linking monomer. This research may contribute to improve air pollution caused by volatile of cross-linking monomers. H-nuclear magnetic resonance (1H-NMR) and Fourier transform infrared spectroscopy (FT-IR) were used to characterize.
