In this paper, a kind of titanium-doped silicone prepolymer(TDS) was modified by hydroxyl-terminated saturated polyester (HTSP) by condensation polymerization. By Fourier Transform Infrared Spectroscopy (FTIR) the reaction of ethoxy groups of the TDS prepolymer with hydroxyl groups of the HTSP during condensation polymerization process was confirmed. The resins were cured with blocked polymeric isocyanate. The influence of the HTSP content on the properties of the modified resins such as thermal stability, corrosion resistance, as well as mechanical and other properties, were discussed in detail. The results showed that the properties of the resins were improved greatly after modification, and the optimal mass ratio of TDS to HTSP in the modified resins was 1:1. Thermogravimetry analysis (TGA) studies indicated that the weight loss of this sample(wTDS : wHTSP =1:1) was not obviously below 400°Cand the impedance value of this coating was significantly higher than that of the others.
