| Abstract: | Polysilazane(PSZ) fibers with an excellent spinnability, which are suitable for irradiation crosslinking, were prepared from Me 2SiCl 2 and MeHSiCl 2 by a co ammonolysis, polymerizing and melt spinning method. PSZ fiber were crosslinked and cured by electron beam(EB) irradiation. Influences of reactants ratio, reaction temperature and reaction time on the spinnability of PSZ, and those of absorbed doses on the melting point, gel content, thermo gravimetric (TG) curve and cermic yield of the PSZ fibers, were studied. The mechanism of the irradiation crosslinking of PSZ fibers was analyzed. |
| Keywords: | polysilazane fiber irradiation crosslinking curing electron beam |
