摘　　要：以对羟基苯甲酸、烯丙基溴、含氢硅油为原料,通过取代、硅氢加成反应,合成了柔性连接基为—CH2CH2CH2O—、端基为羧基的侧链聚硅氧烷液晶中间体M1;然后又以对羟基苯甲酸、氯乙醇、丙烯酸和含氢硅油为原料,通过取代、酯化、硅氢加成反应,合成了柔性连接基为—CH2CH2COOCH2CH2O—、端基为羧基的侧链聚硅氧烷液晶中间体M2。经红外表征证实为目标产物。The related side-chain polysiloxane liquid crystalline intermediate M1 with —CH2CH2CH2O— was synthesized through etherification and the grafting reaction with p-hydroxy benzoic acid,allyl bromide,hydrogen silicone oil.Then the side-chain polysiloxane liquid crystalline intermediate M2 with —CH2CH2COOCH2CH2O— was obtained through substitution,etherification and grafting reaction with p-hydroxy benzoic acid,chloroethanol,acrylic acid and hydrogen silicone oil.The structures of the compounds were characterized by IR,which confirmed with the attributes of the target product.
