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.
