摘　　要：从硅橡胶与耐热助剂相容性出发,以氢氧化钾催化下环三硅氧烷开环聚合得到的聚有机硅醇钾、甲基封端的二甲基聚硅氧烷、氯化铈为原料合成了POSC。探讨了其反应过程,并通过红外光谱和硅-核磁共振谱表征了产物的分子结构,结果表明POSC为含铈聚有机硅氧烷。To improve the compatibility of silicone rubber and the heat-resistant additives, polysiloxane containing cerium (POSC) was synthezised using potassium siloxanolate prepared from hexamethylcyclotrisiloxane at the catalysis of potassium hydroxide, trimethylsilyl endblocked dimethylpolysiloxane and anhydrous cerium chloride. The structure of polysiloxane containing cerium (POSC) was characterized by FTIR and Si-NMR.
