Abstract
The reaction products of short-chain ammonium polyphosphate and phosphoric acid were studied in order to synthesize inorganic polyoxides with relaxation properties close to those of elastomers. The concentration dependence of the melting and softening temperatures of the formed compositions is investigated. It is shown that at concentration of phosphoric acid higher than 15 wt.% of the ammonium polyphosphate content, the obtained compounds are water-insoluble viscous mixtures with a heat resistance of 295±5 °C. Glass transition temperature Tg = −80.9±6.2 °C, melting point Tm = −65.4±3.1 °C were observed for a composition with 30 wt.% of phosphoric acid, while these value were Tg = −70.6 °C and Tm = −53.4 °C for a composition with a 50 wt.% content of phosphoric acid.
