Abstract
Tris-and hexa-substituted polyimide resin matrixes based on cyclotriphosphazene were prepared from hexakis(4-aminophonexy) cyclotriphosphazene and Maleic anhydride. The products were structurally characterized by FT-IR, H, P, C NMR spectroscopy and elemental analysis. TGA and DTG analysis show that the hexa-substituted and tri-substituted polyimide exhibits perfect heat-resistancy ,with initial decomposition temperature up to 409. 36℃ and 396. 95℃ respectively and the residual char at 800℃ to 65. 23% and 73. 78% ,so they were suitable to use as heat-resistant composite matrices for rocket and missile.关键词
