| 41 | Brominated and epoxidized flame retardants | US12825591 | 2010-06-29 | US08569424B2 | 2013-10-29 | Erin B. Vogel; Shari L. Kram; Daniel J. Murray; Bruce A. King |
| Brominated and epoxidized organic compounds are useful flame retardants for polymers such as polystyrene. The organic compounds contain both bromine and oxirane groups, and have molecular weights of at least 1500. The brominated and epoxidized organic compounds can be prepared by sequentially brominating and epoxiding (in either order) a starting compound that contains multiple non-conjugated carbon-carbon double bonds. | ||||||

| 43 | Process for Recovering Brominated Styrene-Butadiene from a Bromination Reaction Solution | US13818859 | 2011-09-19 | US20130178547A1 | 2013-07-11 | John W. Hull, JR.; Bruce A. King, JR.; Shari L. Kram; Joseph J. Kiefer |
| Brominated styrene-butadiene copolymers are recovered from solutions in a halogenated solvent by an anti-solvent precipitation process. The precipitation process is performed by adding the anti-solvent to the brominated styrene-butadiene copolymer solution. By performing the precipitation using this specific order of addition, a denser product is obtained that is easier to dry. The recovered product shows a reduced tendency to act as a nucleating agent when it is used as a flame retardant additive in an extrusion foaming process. | ||||||

It also complies with the relevant regulations regarding ship-shell paints. Moreover, it is easy to carry out and is suitable for industrialization. | ||||||

| 48 | PROCESS FOR BROMINATING UNSATURATED ORGANIC COMPOUNDS WITH REMOVAL OF QUATERNARY AMMONIUM OR QUATERNARY PHOSPHONIUM MONOCHLORIDES | US13257999 | 2010-02-02 | US20120016088A1 | 2012-01-19 | David B. Gorman; Douglas C. Greminger; Ronald B. Leng |
| Unsaturated organic compounds are brominated with a quaternary ammonium tribromide or a quaternary phosphonium tribromide, especially when the bromination is conducted in a chlorinated solvent. A quaternary ammonium or quaternary phosphonium monobromide salt is produced in the reaction, together with some amount of quaternary ammonium or quaternary phosphonium monochloride salt. The monochloride salt is converted to the corresponding quaternary ammonium monobromide salt by reacting it with a source of bromide ions. The monobromide salt is then reacted with bromine to regenerate the quaternary ammonium or phosphonium tribromide, which is recycled into the bromination reaction. This process reduces the amount of chlorine that is incorporated into the brominated product. | ||||||
| 49 | Process for recovering brominated butadiene polymers from solution | US12146636 | 2008-06-26 | US08058389B2 | 2011-11-15 | Ronald B. Leng; Avani M. Patel; Brian D. Scherzer; Derrick G. Wetters; Douglas C. Greminger |
| Brominated polybutadiene polymers are recovered from a bromination reaction solution by forming the solution into droplets, thermally stripping the solvent from the droplets, and then washing the resulting particles. The washed particles are then recovered from the washing liquid. The droplets can be dispersed into a gaseous medium such as air and then transferred into a nonsolvent liquid for washing, or can be formed directly into the nonsolvent liquid. The process forms a particulate polymer material that is easily filterable and has low levels of volatile impurities and inorganic salts. Brominated polybutadiene polymers recovered in this manner are often very thermally stable. | ||||||
| 50 | PROCESS FOR FORMING AND DEVOLATILIZING BROMINATED POLYBUTADIENE POLYMER PARTICLES | US13057251 | 2009-08-18 | US20110143030A1 | 2011-06-16 | Douglas C. Greminger |
| Brominated butadiene polymers are recovered from solution and formed into particles by spraying the solution onto a heated, mechanically agitated bed of seed particles. The droplets contact the seed particles in the bed and form a polymer layer on the outside of the seed particles, thereby enlarging them. The solvent is removed from the droplets after they make contact with seed particles in the bed. The process allows for the simultaneous removal of solvent and formation of somewhat large particles. The process forms at most small amounts of agglomerates and fines. | ||||||
| 51 | PROCESS FOR BROMINATING BUTADIENE COPOLYMERS BY THE ADDITION OF WATER OR CERTAIN SOLVENTS | US12866992 | 2009-02-25 | US20110021715A1 | 2011-01-27 | David Bruce Gorman |
| Butadiene copolymers are brominated using certain quaternary ammonium tribromides as the brominating agent. The bromination process proceeds easily under mild conditions, and produces a brominated product that has excellent thermal stability. A quaternary ammonium monobromide salt is produced as a reaction by-product. A solvent for the monobromide salt is added to the reaction after 25-90% bromination of the aliphatic carbon-carbon double bonds. This provides for significantly shorter reaction times while providing a product with few impurities. | ||||||

| 56 | Higher modulus compositions incorporating particulate rubber | US609520 | 1996-03-01 | US5693714A | 1997-12-02 | Bernard D. Bauman; Mark A. Williams; Reza Bagheri |
| Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles. | ||||||
