摘要：p-Xylylene diazide (XDA) and dipropargyl ether of bisphenol A (DPEBPA) were synthesized and then a novel polytriazole, poly(4,4'-(propane-2,2-diyl) diphenyl-oxy-methylene-1,5 (and 1,4)-(1,2,3-triazole)-p-xylene), was prepared from XDA and DPEBPA by 1,3-dipolar cycloaddition polymerization and characterized by FTIR, H-1-NMR, GPC, DSC, WAXD, TGA, etc. The results show that the polytriazole with the number average molecular weight of 9.77 x 10(4) is a partially crystalline polymer. The tensile strength and tensile modulus of the polytriazole film are 72.9 MPa and 2.95 GPa, respectively. The glass transition temperature of the polymer is 93.6 degrees C and thermal decomposition temperature arrives at 350 degrees C.
