A Synthesis Process of Methoxy-terminated Phenyl Methyl Silicone Resin Prepolymer
A methoxy-terminated phenyl methyl silicone prepolymer was prepared by the hydrolysis-condensation reaction of phenyltrichlorosilane,dimethyldichlorosilane,methanol and water.The effects of parameters,such as hydrolysis and feeding methods,solvents,reaction time,and temperature,on reaction process and product properties were investigated.By characterizing the composition,structure,and performance of the prepolymer,the optimal reaction conditions for preparing liquid silicone resin prepolymer were determined.
