Abstract : In continuing research toward the development of thermally stable polymers based on the boron-tophosphorus bond system, experiments were conducted to find means of improving the thermal stability of linear phosphinoborine (borophane) polymers, and to introduce a variety of boron substituents into the linear and cyclic polymers. An investigation of the boron-to-nitrogen bond system led to two series of polycyclic borazene polymers one directly bonded and the other bonded through oxygen. Screening experiments on themally stable polymers systems based on phosphorus-to-nitrogen, phosphorus-to-oxygen- tosilicon, and carbon-to-oxygen-to-silicon bond systems were conducted.
