Chalcogenide hybrid inorganic organic polymers with medium and long wavelength infrared transparency
By reacting elemental sulfur with deuterated co-monomers via inverse vulcanization, the challenges of low transparency in MWIR and LWIR imaging are addressed, resulting in CHIPs with improved optical properties and thermomechanical performance.

Abstract
A composition includes a polymer that is a reaction product of a co-monomer and one or more of elemental sulfur or a chalcogenide halide, wherein the co-monomer includes a vinyl monomer, isopropenyl monomer, acryl monomer, methacryl monomer, unsaturated hydrocarbon monomer, epoxide monomer, thiirane monomer, alkynyl monomer, diene monomer, butadiene monomer, isoprene monomer, norbornene monomer, amine monomer, thiol monomer, sulfide monomer, alkynyl unsaturated monomer, nitrone monomer, aldehyde monomer, ketone monomer, ethylenically unsaturated monomer, styrenic monomer, or a mixture of any two or more thereof; and the co-monomer comprises one or more deuterium atoms.
