Abstract Polysulfides (PS) are emerging S-rich materials with unique properties attractive for various applications including Hg2+ capture. However, PS have yet to offer competitive Hg2+ binding capacities (q) due to their poor hydration and intractable structures. Herein, neoteric PS were developed by reacting molten sulfur with oxygenous co-monomers containing acryl-, methacryl-, and allyl groups. The PS products were thoroughly examined in terms of their consistency, rheology, solvent solubility, hydrophilicity and morphology. Their composition and chemical structures were proposed based on elemental analysis, FTIR, GC-MS, 2D NMR (HSQC) and XPS analyses. The best PS achieved high q ~ 835 mg g−1 (vs. q
