摘　　要：以苯基三氯硅烷和丙基三氯硅烷为原料，通过水解、缩聚反应，得到固体苯基丙基硅树脂。采用1HNMR和FT—IR光谱对产物进行了表征，重点讨论了影响苯基丙基硅树脂收率的主要因素。确定最佳合成工艺为：苯基三氯硅烷与丙基三氯硅烷的量之比为2：1、搅拌速度400r／min、水解温度7～10℃、溶剂与水的质量比1．5：1，水解反应时间2h，缩聚反应时间由所需的苯基丙基硅树脂的羟基含量决定。Propyphenyl silicone resin was prepared by hydrolysis and condensation from phenyltrichlorosilane and n-propyhrichlorosilane and characterized by ＇ H NMR and FT-IR spectra. The factors for the preparation yields provided a optimal reaction condition at a phenyltrichlorosilane to n-ropyltrichlorosilane molar ratio of 2：1, a stirring speed of 400 rpm, and a hydrolysis temperatures of 7 - 10 ℃, a solvent to water weight ratio of 1.5：1 for a 2 hour condensation. Propyphenyl silicone resins with different hydroxy contents were obtained by controlling the polycondensation time.
