HIGH POLYMERIC MATERIALS
Abstract
Polymerization of the phosphonitrilic isothiocyanates occurs readily. The phosphonitrilic bromides react with both Grignard reagents and organolithium compounds, but the intermediates thus formed have not yet been decomposed to yield reasonable quantities of organophosphonitrilic derivatives. The syntheses of trimeric and tetrameric phosphonitrilic fluorides by metathetical reactions of the chlorides with sodium fluoride in nitrobenzene were effected. A new reaction between the completely fluorinated compounds and aryllithium compounds gives stepwise substitution of the fluorine atoms by aryl groups. Three main problems involving coordination polymers were investigated: (1) Attempts to link betadiketone complexes together failed because substituent groups on the chelate rings are unreactive. (2) Triethylenediamine was shown to coordinate through both of its nitrogen atoms, thus to form polynuclear complexes. (3) The compositions, solubilities, and heat stabilities of a number of complexes of bis-beta-diketones with bivalent, 4-covalent metals were studied. (Author)
