Drying of the gel yielded a rubbery material (Tg = -2 ºC) with a degradation profile that shows a similar onset of degradation (Td,5% ca. 160 ºC) as the linear parent polymer but some higher thermal stability above 200 ºC (ESI Figure ). Comparative rheological analysis of linear and crosslinked polymer shows an increasing gap (G' -G'' with G' > G'') between the elastic (G') and viscous (G'') component, further substantiating successful crosslinking (ESI Figure ). Importantly, the rheological profile of the material in the amplitude sweep test was affected by the amount of tetra-thiol crosslinker, which suggests some tunability of the mechanical properties of our materials (ESI Figure ). The crosslinked material is yellow and optically transparent (vide infra), shows a good refractive index (RI = 1.63) and an Abbe number of 30, potentially rendering it interesting for optical applications. Furthermore surfaces can be easily covered with it via dip-coating (ESI Figure ). Exposing the dried gel materials to DCM (a good solvent for the parent polymer) resulted in swelling but not dissolution, as expected. Determination of the sol-gel fraction suggested that the gel contained 85wt% of the initial material while the soluble portion contained the dt-c5c by-product from the ROTERP stage (ESI Figure ). Although covalent network structures (usually) impede solution processing, we thought that here thermal reprocessing could be feasible due to the dynamic nature of the polysulfide bonds. Indeed, hot-pressing of the granulated material could be achieved at 80 ºC to yield a selfstanding and homogenous film (see Figure ). Adding an extra Lewis base such as NEt3 to the network promoted faster reprocessing at a given temperature and pressure (ESI Figure ). The possible thermal reprocessing further implies that these disulfide-crosslinked materials should be degradable by similar exchange reactions with small molecules. Accordingly, treatment of a crosslinked sample, which remained stable in DCM for weeks, with i BuSH and NEt3 caused break down of the network within minutes (see supplementary video in the ESI), a property which is for example also useful in the context of thiol sensing.
