FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing polycarbosilanes. Disclosed is a method of producing polycarbosilane via thermal decomposition of polydimethylsilane in the presence of zirconium tetrachloride in an inert atmosphere at excess pressure of 0.4-0.5 MPa in three steps: holding at 350-380°C for 2-10 hours, releasing low-boiling point components and then holding at 350-420°C for 20-30 hours.
EFFECT: method of producing polycarbosilane which enables to cut time and lower temperature of the process.
