Abstract : Boron-based polymers stable to 1000 F were prepared:-(OP(Ph)2B10H12(Ph)2P-), (POP-1); (=P(Ph) 2CH2CH2(Ph)2P=NP(Ph)2-B10H12(Ph)2PN=),(PNP-I); and (=P(Ph)2-benzo-(Ph)2P=NP(Ph)2B10H12(Ph)2PN=), (PNP-II). Solubility studies indicated that Nmethylpyrollidone would be a suitable solvent.All 3 materials evolved H on heating. Evolution of H began at 270 C for POP-I, at 240 C for PNP-I and at 320 C for PNP-II. Continued heating to 350 C showed 4 moles of H per B10H12 unit were evolved. No further gas evolution occurred on prolonged heating at this temperature. Heating to 500 C effected the evolution of a small amount of H and traces of benzene. PNP-II went through a semi-solid state at 320-340 C. Clear, adherent coatings on steel and Al were formed with POP-I. PNP-II laminates with asbestos, carbon and refrasil fillers appeared promising.
