Tailoring the properties of guaiacol-derived high sulfur-content materials through post-polymerization modification with dithiols

High sulfur content material (HSM) prepared from biomass-derived guaiacol and elemental sulfur (GS80) was modified with dithiols at varying mass ratios. Dithiol modification allowed tuning of the material properties, such as a predictable relationship between glass transition temperature and proportion of added dithiol. Dithiol modification is thus a promising new strategy for customized HSMs.
