ABSTRACT:
The invention provides a novel organoborosilicon polymer comprising two types of the recurring monomeric units represented by the general formulas of, one, --SiR.sup.1.sub.2 --CH.sub.2 -- and, the other, --BR.sup.2 --NR.sup.3 --, in which R.sup.1, R.sup.2 and R.sup.3 are each a hydrogen atom or a monovalent hydrocarbon group. Such an organoborosilicon polymer is readily prepared by the thermal decomposition polymerization reaction of an organopolysilane compound and a borazine compound at 250.degree. to 500.degree. C. and useful as a precursor of an inorganic ceramic material or inorganic fibers or as a binder of ceramics.
