| Abstract: | A hydroxyl-terminated saturated polyester was chemically modified by titanium-doped silicone pre-polymer through condensation polymerization.The structure of the modified polyester resin was characterized by Fourier-transform infrared spectroscopy.The polyester resins were cured with blocked polyisocyanate as curing agent.The physicomechanical properties,thermal resistance and corrosion resistance of the film were tested.The results revealed that the modified polyester has good physicomechanical properties.... |
