Abstract: In this contribution, novolac modified by CSEB ceramic precursor (B,B,B-tris[(chlorodimethylsilyl)-ethane]borazine, CSEB) was synthesized successfully. The corresponding molecular structure, chemical state and thermal property were characterized by FT-IR, Raman spectra, XPS, NMR and TGA. Meanwhile, DTA/TG/MS… read more here.
