Abstract
These studies showed that the conditions of synthesis and properties of polycarbosilane are a function of the purity of the stating polydimethylsilane, and the technical requirements for its quality were elaborated as a result of this. The temperature—time parameters of synthesis (350–380°C, 3–8 h) and concentration of promoter — polyborodiphenylsiloxane (1 wt. %), were determined for fabrication of stably formed polymers. The criteria for the end of synthesis and obtaining a polymer with the required degree of branching were established. The preliminary technical requirements for fiber-forming polycarbosilane were formulated.
