Study on the melt spinnability of polyborosilazane
关键字：SiBN ceramic fiber; preceramic polymer; rheological property; melt spinnability
Dynamic shear rheology of polyborosilazane (PBSZ) synthesized at 130°C from single-source precursor Cl3Si-NH-BCl2 (TADB) was studied in the paper. The results showed that PBSZ exhibited non-Newtonian behavior, this is usually requirement for&nb...
