Thermal Stability of a Novel Polytriazoleimide

Abstract:

A new polytriazoleimide (PTAI) was prepared from 1,2,3-triazole-containing diamine and 4,4’-(hexafluoroisopropylidene) diphthalic anhydride by polycondensation. The thermal stability was investigated. The PTAI was pyrolyzed at 400 °C and 750 °Cseparately and the pyrolysis was traced by the Py/GC/MS combined technique. Nitrogen and related compounds which result from the cleavage of C-N and N-N bonds in the polymer are found in the pyrolysis products at 400 °C. The further decomposition of PTAI would take place at imide rings and the chain units between imide rings at 750 °C. A degradation mechanism of the PTAI is proposed.
