Abstract: Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the S—S bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.

Abstract: Sulfur composites and polymeric materials having a high sulfur content and prepared from elemental sulfur as the primary chemical feedstock. The sulfur copolymers are prepared by the polymerization of elemental sulfur with one or more monomers of amines, thiols, sulfides, alkynylly unsaturated monomers, nitrones, aldehydes, ketones, thiiranes, ethylenically unsaturated monomers, or epoxides. The sulfur copolymers may be further dispersed with metal or ceramic composites or copolymerized with elemental carbon, photoactive organic chromophores, or reactive and solubilising/biocompatible moieties. The sulfur composites and polymeric materials feature the ability self-healing through thermal reformation. Applications utilizing the sulfur composites and polymeric materials may include electrochemical cells, optics, H2S donors and antimicrobial materials.

Abstract: Copolymerization of elemental sulfur with functional comonomers afford sulfur copolymers having a high molecular weight and high sulfur content. Nucleophilic activators initiate sulfur polymerizations at relative lower temperatures and in solutions, which enable the use of a wider range of comonomers, such as vinylics, styrenics, and non-homopolymerizing comonomers. Nucleophilic activators promote ring-opening reactions to generate linear polysulfide intermediates that copolymerize with comonomers. Dynamic sulfur-sulfur bonds enable re-processing or melt processing of the sulfur polymer. Chalcogenide-based copolymers have a refractive index of about 1.7-2.6 at a wavelength in a range of about 5000 nm-8μιτι. The sulfur copolymer can be a thermoplastic or a thermoset for use in elastomers, resins, lubricants, coatings, antioxidants, cathode materials for electrochemical cells, dental adhesives/restorations, and polymeric articles such as polymeric films and free-standing substrates. Optical substrates are constructed from the chalcogenide copolymer and are substantially transparent in the visible and infrared spectrum.

Abstract: Compositions of flame retardants and methods of enhancing char formation in a flame retardant-treated substrate. A base material is combined with a flame retardant to form the flame retardant-treated substrate. The flame retardant contains a sulfur copolymer prepared by the polymerization of sulfur monomers with organic monomers. The flame retardant can be deposited on a surface of the base material, coated on the base material, or mixed into the base material. When the flame resistant substrate is on fire, the flame retardant forms a charring layer on the flame retardant-treated substrate. The charring layer can extinguish and prevent the fire from spreading.

Abstract: 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.
