20140066589 | Method For The Preparation of Poly(Disulfide) Polymers and Gels - High molecular weight disulfide polymers are synthesized in aqueous media by exposing dithiol compounds to a mild oxidizing environment in the presence of a tertiary amine catalyst. The unique oxidizing system polymerizes monomers through the formation of sulfur-sulfur bonds between dithiol compounds. The same oxidizing system may be used to make disulfide-crosslinked gels from compounds containing multiple thiol groups. The oxidizing system is comprised of oxygen at atmospheric concentration and dilute hydrogen peroxide. A filler such as carbon black may be incorporated into the polymer or cross-linked gel during polymerization. A polydisulfide polymer is provided having a weight average molecular weight of greater than about 100,000 g/mol and a polydispersity index of about 2 or less. A tetrathiol composition results from a reaction of a diacrylate with a trithiol. The tetrathiol composition may be subjected to an oxidizing environment with a tertiary amine catalyst to provide a polytetrathiol polymer network. | 03-06-2014 |
20140100351 | SOYBEAN BASED FIBERS - Fibers can be formed from monomers derived from a biorenewable source. In an embodiment, a fiber forming composition that includes a monomer or mixture of monomers with at least one monomer being derived from a biorenewable source in placed in a fiber producing device. At least a portion of the fiber forming composition is ejected through an opening of the fiber forming device. The ejected fiber forming composition is subjected to light at wavelengths sufficient to activate a reaction which causes solidification of the fiber as the fibers are ejected from the fiber producing device. | 04-10-2014 |
