Including Synthesis And Application Of Research, Energy Curing Agent

Using pentaerythritol as initiator, boron trifluoride diethyl etherate as catalyst.dichloroethane as dispersion agent, the chloride polyether polyol (A) is synthesized based on the mechanism of cationic ring-opening polymerization of epiclilnrohyclrin.The azide polyether polyol (B) is synthesized, in DMF through A and sodium azide, and the non-reported azide energetic curing agent (C) is synthesized through the adduction of B and IIDI. The relationship of B's thermal degradation and glass transition temperature with the percent of azide substitution is studied. It's found that B is thermally degraded in two steps: first, the azide group degraded at 255.06T' and then the main chain degraded at 346.28'C. With increasing the percent of azide substitution, maximum temperature of thermal degradation is also increscent, a linear relationship exists between the glass transition temperature of B and percent of azide substitution. The energetic curing agent C has good physical compatiblity with GAP. GAP/C system also has good physical and chemical compatiblity with TEGDN. The tensile strength /elongation of break of GAP/C test is 0.7 MPa/129%, which is better than GAP/N100 (0.5MPa/56.5% in literature). The energetic curing agent C has potential application.
