DYNAMIC COVALENT POLYMERIZATIONS WITH ELEMENTAL SULFUR AND SULFUR PREPOLYMERS
An iterative approach to dynamic covalent polymerizations of elemental sulfur with functional comonomers to prepare sulfur prepolymers that can further react with other conventional, commercially available comonomers to prepare a wider class of functional sulfur polymers. This iterative method improves handling, miscibility and solubility of the elemental sulfur, and further enables tuning of the sulfur polymer composition. The sulfur polymers may be a thermoplastic or a thermoset for use in elastomers, resins, lubricants, coatings, antioxidants, cathode materials for electrochemical cells, and polymeric articles such as polymeric films and free-standing substrates.
