Antimony polymers, part 2 - Physical, chemical and thermal properties

Three antimony-containing polymers (P-1, P-2, P-3) were synthesized by reacting triphenyl antimony dinitrate with bisphenol A (P-1), with tetrabromobisphenol A (P-2) and with N,N'-bis(4-hydroxybenzylidene)-oxydianiline (P-3) Solubility, density, chemical and thermal stability of these antimony polymers have been evaluated. The polymers are only soluble in dipolar aprotic solvents like dimethyl sulfoxide, dimethylformamide, dimethylacetamide, etc., and have relatively high densities (1.2-1.8 g cm(-3)). The solubility parameters (delta) and chemical stability of the polymers were studied in different chemical environments. The thermal properties of the polymers have been studied by thermogravimetric analysis, differential thermal analysis and isothermal gravimetric analysis.
