High temperature thermosets/ceramics from novel hybrid copolymer containing random distribution of boranyl, silyl, or siloxyl, and acetylenic units

摘要

Novel class of organoboron thermosetting polymer and ceramics that are formed from an organoboron 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 interdispersed block-type structures of each unit. The thermosetting polymers are useful as high temperature, oxidatively stable thermosetting plastics and for microelectronic applications.
