Abstract: Epoxy rosin-terminated silicone polymer was prepared by acylation reaction of hydroxyl silicone oil and epoxy rosin chloride which was synthesized with rosin as raw material and used dimethylformamide as solvent.The effects of reaction temperature and materiel molar ratio on the reaction were studied,and the structure of product was characterized by FT-IR and thermogravimetry(TGA).The experimental results showed that when the epoxy rosin chloride and hydroxyl silicone oil mass ratio was 2.2∶1,the amount of pyridine was 10% of rosin chloride(wt,the mass fraction),the yield of silicone polymer was 90.1%,the viscosity was 158.2mPa·s and the epoxy value reached 0.156mol/100g,under the reaction condition of 3 hours at 40℃.The Infrared spectroscopy (FT-IR) and epoxy value analysis showed that the epoxy rosin was introduced in polysiloxane structure,TGA indicated that the epoxy rosin terminated silicone polymers had good thermal stability.
