Organosoluble polyimides with tetramethyldisiloxane fragments in the main chain were synthesized by one-step high-temperature polycondensation and their properties were studied. Heat resistant polymers (Tg = 195–240 °C, T10% = 420–490 °C) were tested as protective coatings for quartz optical fibers. The new developed coatings have high thermal (72 h at 300 °C) and hydrolytic stability.

含硅聚酰亚胺:作为光纤光导涂层的合成、性能和应用

采用一步高温缩聚法合成了主链含四甲基二硅氧烷片段的有机可溶性聚酰亚胺,并对其性能进行了研究。耐热聚合物(Tg = 195–240 °C,T10% = 420–490 °C)被用作石英光纤的保护涂层。新开发的涂层具有很高的热稳定性(在 300°C 下为 72 小时)和水解稳定性。
