| Abstract: | The curing of process polyselazane (PSZ) fibers by using boron trichloride(BCl3 )was studied.The influence of the treating conditions on the reaction were dissussed and the mechanism was analysed. The results show that the reaction of BCl3 react with N-H and Si-H bends in the PSZ fibers, which leads to the crosslinking between the molecules in the fibers by the formation of N-BN bonds. The infusibilization was achieved under suitable conditions such as concentration of BCl3, treating temperature and time, while incorporating the desired beron. |
