Abstract
In this work, a series of poly(aryloxyphosphazenes) with different molar ratios of aryloxy and co-substituted n-butoxy (PBPP) are prepared and the effects of addition sequence of two nucleophilic reagents and reaction temperatures on the structure of resulted PBPP are investigated. The effect of n-butoxy groups on reducing glass transition temperature (Tg) of the polymers is confirmed by DSC. Both PBPP matrix and its composites with inorganic fillers (with only the addition of inorganic oxides, such as fumed silica and zinc oxide) reinforcements possess low Tg of −61.4 °C and −55 °C respectively. Ablative properties of the PBPP composites are characterized by oxy-acetylene ablation tests and it exhibited linear ablation rates of 0.14 mm·s−1. Meanwhile, performance of PBPP composites for electrical insulation is evaluated and showed breakdown strength of 26.99 kV·mm−1 and flashover voltages of 14.90 kV under AC voltages.
