  • Publication number: 20130079472
    Abstract: Butadiene polymers are brominated using tetraethylammonium tribromide as the brominating agent. The bromination is performed in a solvent for the starting polymer and for the tetraethylammonium bromide that is formed as a reaction byproduct. The process proceeds easily under mild conditions. In some cases, a solution of the brominated polymer and the tetraethylammonium monobromide is produced; this solution separates into a layer that contains the brominated polymer and another layer that contains most or all of the tetraethylammonium monobromide salt. In other cases, the brominated polymer precipitates from the reaction mixture and is separated from the tetraethylammonium monobromide salt in that manner. This process therefore permits the tetraethylammonium monobromide reaction by-product to be separated easily from the brominated product, and allows aqueous washing steps to be reduced or eliminated.

  • Patent number: 8017694
    Abstract: Nonconjugated conductive polymers, which are all polymers that have a ratio of double bonds to total bonds of less than ½ are doped with iodine to produce compositions with unexpected characteristics in this invention. The mechanical and elastomeric properties of a nonconjugated polymer can be enhanced by doping the polymer with an electron acceptor such as iodine, in order to cure the polymer. Among the nonconjugated polymers are the cis-1,4-polyisoprene, cis-1,4 polybutadiene, styrene-butadiene copolymers (SBR), ethylene-propylene-diene monomer and poly (?-pinene). A heated mixture of iodine and sulfur produces a faster rate of vulcanization of rubber than using sulfur alone.

  • Patent number: 7897654
    Abstract: In one aspect, the invention relates to silicone prepolymer compositions comprising a silicone prepolymer and a solvent. A soluble silicone prepolymer can be provided having increased average silicon content, thereby attaining a desired oxygen permeability. A solvent can be provided with a desired balance between hydrophilicity and hydrophobicity by selection and modification of the solvent molecular structure, resulting in molded polymer films and articles that exhibit minimal or nonexistent eye irritation and exhibit highly transparent products. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

  • Patent number: 7674862
    Abstract: Brominated butadiene polymers are recovered from a bromination reaction solution by partially stripping the solvent to form a concentrated solution or slurry, and then recovering the brominated butadiene polymer from the concentrated solution or slurry. The process allows for a simplified, effective an economical recovery of the brominated butadiene polymer. Brominated butadiene polymers recovered in this manner are often very thermally stable.
