Abstract Converting elementary sulfur into sulfur-rich polymers provides a sustainable strategy to replace fossil-fuel-based plastics. However, the low ring strain of eight-membered rings, i.e., S 8 monomers, compromises their ring-opening polymerization (ROP) due lack an enthalpic driving force and as consequence, poly(sulfur) is inherently unstable. Here we report that copolymerization with cyclic disulfides, e.g., 1,2-dithiolanes, can enable simple energy-saving way convert...
