Novel class of organoboron thermosetting polymer and ceramics that are formed from an organohoron polymer having a backbone with a repeating of at least one alkynyl group, at least one silyl group, at least one boranyl group optionally at least one siloxyl group. and optionally an aryldisilyl group. The boron containing units in and the silIcon containing units can be arranged in either random occurrences between each other or in the form of interdis- persed block-type structures of each unit. The thermosefling polymers are useful as nigh temperature, oxidatively stable thermosetting plastics and for microelectronic applications.
