The experimental results show that the yield of product is up to 87% when the molar ratio ofEHPOS : CA : ATS is 1 : 1.05 : 1.1. EHPOS and CA were maintained at 115 ℃ for 3 hours, then after cooling the reaction solution to 75 ℃, ATS was added and reacted for another 3.5 hours at 145 ℃. The structure of the product and thermal properties were characterized by Fourier transform infrared (FTIR) and thermogravimetric analysis (TGA), respectively. Results show that fluoride-containing organic silane has excellent thermal stability below 185℃.展开更多
