Abstract
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.
