B-P Polymers: A series of new linear poly-P-methyl-n-alkyl-borophanes were prepared and evidence suggests depolymerization of these materials proceeds by loss of monomer units at the chain ends. A number of new P-substituted triborophane derivatives were prepared as well as several partially B- halogenated derivatives of P-hexamethyltriborophane. New Approaches to Thermally Stable Polymers: A number of diarylphosphonyl azides, Ar2P(0)N3, were prepared and characterized. The azides react with trivalent P compounds to yield phosphoranes. Inorganic Polymer Components: New IR spectra of (R2PBH2)3 compounds have structural implications bearing upon the theory of their stability. IR spectra also confirm the structure (CF3HP0 0H)2, relating to the question of the stability of possible polymers having phosphinic-anhydride connections. Trifluormethyl acetoxyphosphines offer a route to P-O-P bonding and to (CF3PO)n polymers.
