METHOD FOR PRODUCTION OF POLYCARBOSILANE Russian patent published in 1998 - IPC

Abstract RU 2108348 C1

FIELD: production of inorganic fibers and other articles comprising silicium carbide. SUBSTANCE: polycarbosilanes are prepared by thermal decomposition of polydimetylsilane which takes place at pressure 1.5-6 atm. Then sustaining within 2-10 h at 350-380 C is carried out and low-boiling components are removed. Thus obtained products are allowed to stand at 390-450 C within 30-80 h. EFFECT: improved efficiency of the method. 2 dwg, 1 tbl
