Synthesis and Characterization of a Novel Polytriazole

Abstract

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, 1H‐NMR, GPC, DSC, WAXD, TGA, etc. The results show that the polytriazole with the number average molecular weight of 9.77×104 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°C and thermal decomposition temperature arrives at 350°C.
