Organoborosilicon polymer and a method for the preparation thereof

摘要

The invention provides a novel organoborosilicon polymer comprising two types of the recurring monomeric units represented by the general formulas of, one, -SiR12-CH2- and, the other, -BR2-NR3-, in which R1, R2 and R3 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 DEG to 500 DEG C. and useful as a precursor of an inorganic ceramic material or inorganic fibers or as a binder of ceramics.
