Book Description
The synthesis of new phosphorus-containing polymers expected to have high thermal stability was the object of this research. Accompanying this effort has been a study of model compounds and prototype reactions, to obtain information on bond formation and bond stability. Among phosphorus-containing compounds, those containing the P-C-P linkage have unusual thermal stability. For example, several methylene and phenylene bis diphenylphosphine oxides are stable to 425-450 C (797-842 F). For this reason, the preparation of p-c-p type polYmers by addition and condensation reactions using a variety of monomers under Widely varied conditions was attempted. Fundamental studies of the chemistry of P-C compounds are described. Reorganization studies indicated that the CeHs-P bond is probably stable to at least 400 C. Polymers of the polyamide type with phosphorus in the backbone are described. Some prepared from a bibenzimidazole were stable to 425-450 C. (797-842 F), albeit of low molecular weight. Model compounds containing the phosphorus-imidazole bond showed stabilities as high as 500 C. (932 F).
