摘　　要：以苯基三甲氧基硅烷和六甲基二硅氧烷为主要原料,研究了黏度19~30 mm^(2)/s、折射率1.458~1.462的三甲硅基封端苯基硅氧烷低聚物的合成方法,以及单官能团链节M与三官能团链节T物质的量之比(M/T)、回流时间、蒸馏温度等条件对产品黏度、收率和甲氧基残留的影响。确定最佳合成条件为M/T=2.05,回流反应6 h,110℃蒸馏3 h,产品收率最高92.3%,黏度19.8 mm^(2)/s,折射率1.463,无色无味。The trimethylsilyl terminated phenylsiloxane oligomers with a viscosity of 19-30 mm^(2)/s and a refractive index of 1.458-1.462 were synthetized,with phenyltrimethoxysilane and hamethyldisiloxane as the main raw materials.The effects of the factors on product viscosity,yield,and methoxy residues have been investigated,including M/T ratio,reflux time,distillation temperature.The optimal synthesis conditions are determined as follows:M/T ratio is 2.05,reflux for 6 hours,and evaporate at 110℃for 3 hours.Thus the oligomer is a colorless,odorless,with a maximum yield of 92.3%,viscosity of 19.8 mm^(2)/s,and refractive index of 1.463.
