摘　　要：以丙酮与苯基三氯硅烷为原料、氯化亚铜为催化剂、三乙胺为缚酸剂、苯为溶剂,合成了苯基三异丙烯氧基硅烷。当反应温度为50°C时,产品收率在43%左右。通过红外、核磁共振氢谱和碳谱及裂解质谱对产物结构进行了表征;并将其作为交联剂,配成了脱丙酮型室温硫化硅橡胶,硫化后的硅橡胶具有较好的介电性能和机械性能。Phenyltriisopropenyloxysilane was synthesized with cuprous chloride as catalyzer, triethylamine as deacid reagent, acetone and phenylrichlorosilane as raw materials. The product yield was 43% when the reaction temperature was 50℃. Its microstructure was analyzed and characterized by FTIR, 1H NMR, 13C NMR and MS. The prepared phenyhriisopropenyloxysilane was used as the across-linking agent to prepare deaeetonized room temperature vulcanization （RTV-1） silicone rubber and the vulcanized silicone rubber showed good dielectric and mechanical properties.
