    New Infrared Transmitting Material via Inverse Vulcanization

    Polymers for IR imaging: The preparation of high refractive index polymers (n = 1.75 to 1.86) via the inverse vulcanization of elemental sulfur is reported. High quality imaging in the near (1.5 μm) and mid‐IR (3–5 μm) regions using high refractive index polymeric lenses from these sulfur materials was demonstrated.

    Inverse vulcanization

    Inverse vulcanization is a solvent-free copolymerization process, firstly developed at the University of Arizona in 2013. Because of the high global production of sulfur as a by-product from the crude oil and natural gas refining processes, new methodologies to exploit this resource are under investigation.

    Recently, we have developed a new chemical methodology, termed inverse vulcanization to prepare chemically stable copolymers at small scale using elemental sulfur as a novel feedstock. 28 Inverse vulcanization enables direct bulk copolymerization of liquid sulfur with 1,3‐diisopropenylbenzene (DIB) at 185°C to form chemically stable

    5.2. Inverse vulcanization of elemental sulfur. A major challenge associated with the bulk ROP of S 8 via free radical process was the high temperature required to promote homolytic generation of sulfur radical species (i.e., ∼185 °C) which limited the choice of possible vinylic comonomers that did not volatilize under these conditions.

    Sulfur vulcanization

    Although polymeric sulfur reverts to its monomer at room temperature, polymers consisting mostly of sulfur can be stabilized with organic linkers such as 1,3‐diisopropenylbenzene. This process is called inverse vulcanization and produces polymers where sulfur is the main component. History

    Recent advances in the polymerization of elemental sulphur

    Recent developments in the polymerization of elemental sulfur and the preparation of functional Chalcogenide Hybrid Inorganic/Organic Polymers (CHIPs) are reviewed. CHIPs represent a class of polymers synthesized from elemental sulfur with the incorporation of inorganic chalcogenide components (S, Se, Te) into the organic polymeric backbones.
