We proposed a novel functional polytriazole elastomer (PTE) with thermal stability and adjustable mechanical properties in this article. Attributed to the click chemistry utilized here, the bulk polymerization procedure was conducted efficiently at an amiable temperature. The novel elastomer was considered to be a promising elastomer with low glass transition temperature (Tg < 0°C) and excellent thermal stability (Td5 > 340°C) according to the thermal analysis results. In addition, tensile strength of PTE which ranged from 3.25MPa to 9.49MPa was easily adjusted by controlling the proportion of raw material used in the reaction.
