在聚二甲基硅氧烷中加入不同用量的三(五氟苯基)硼烷[B(C_6F_5)_3],采用TG-IR联用技术对其在N_2中的热分解行为进行研究,结果表明,B(C_6F_5)_3的加入显著降低了聚二甲基硅氧烷的最大热失重温度.聚二甲基硅氧烷中加入10、100ppm(10~(-5)B(C_6F_5)_3,其最大热失重温度从空白样的500℃分别降低到428℃和402℃,分别降低了72℃和98℃.红外光谱表明,B(C_6F_5)-3的加入并没有改变热降解气相产物.

The thermal degradation behavior of polydimethylsiloxane with various content of tri(pentafluorophenl) borane was investigated by TG-IR,the result showed that the introduction of B(C_6F_5)_3 significantly decrease the temperature of maximum mass loss(T_(max)).T_(max) observed for the sample of polydimethylsiloxane with 10 and 100ppm of B(C-6F_5)_3 was 428 and 402℃,which was 72℃and 98℃ lower than that of the blank,500℃,respectively.IR absorptions indicated that B(C_6F_5)_3 brough rio change of the volatile degradation production of polydimethylsiloxane.
