Abstract
Organoboron nitride polymers are produced by polymerization of organoboron nitride compounds having a cyclic structure of the formula (XBNR).sub.3 wherein R represents hydrogen, a saturated or unsaturated alkyl group or an aryl group and X represents a primary, secondary or tertiary amino group or a silylamino group in the presence of at least one of amine compounds of the formula R.sup.1 NH.sub.2 and amine compounds of the formula R.sup.1 NHR.sup.2 wherein R.sup.1 and R.sup.2 which may be the same or different individually represent an alkyl, aryl or silyl group. The organoboron nitride polymers are suitable as a raw material for the production of boron nitride and as a binder for boron nitride powders.

A process of producing an organoboron nitride polymer which comprises polymerizing an organoboron nitride compound having a cyclic structure of the formula (XBNR).sub.3 wherein R represents hydrogen, a saturated or unsaturated alkyl group, or an aryl group and X represents NH.sub.2, NHR.sup.3 or NR.sup.3 R.sup.4 wherein R.sup.3 and R.sup.4 may be the same or different and each represents and alkyl group, an aryl group or a silyl group of -SiR.sup.5 R.sup.6 R.sup.7 where R.sup.5, and R.sup.6 and R.sup.7 may be the same or different and each represents an alkyl group or an aryl group, in the presence of at least one of an amine compound of the formula R.sup.1 NH.sub.2 and an amine compound of the formula R.sup.1 NHR.sup.2 in the range of from 0.003 to 0.3 mol of the organoboron nitride compound wherein R.sup.1 and R.sup.2 which may be the same or different individually represent a C.sub.12 alkyl, a C.sub.18 alkyl or an aryl group.
