Considering the combined monomer scope, our methodology can yield polymers with -Sx-functionalities across an impressive Tg range of ca. 170 ºC. Particularly high Tg polymers exceeding 100 ºC have been challenging to obtain from elemental sulfur as e.g. inverse vulcanisation techniques typically yield low Tg materials. In terms of thermal stability, the vast majority of materials are stable to above 250ºC which represents an approximate 100ºC improvement over previous ROTERP polymers from elemental sulfur which were prone to decomposition via loss of COS as soon as sulfur-sulfur bonds opened. In contrast the polymers reported in this contribution are stable at temperatures where sulfur-sulfur bonds can be thermally activated.
