| 20080227903 | PREPARATION AND PROVISION OF HIGH ASSAY DECABROMODIPHENYLETHANE - High assay, reaction-derived decabromodiphenylethane product is prepared by feeding (i) diphenylethane or (ii) partially brominated diphenylethane having an average bromine number less than about two, or (iii) both of (i) and (ii), into the liquid confines of a reaction mixture. Such reaction mixture is (a) formed from components comprised of excess liquid bromine and aluminum-based Lewis acid bromination catalyst, and (b) maintained at one or more elevated reaction temperatures of from about 45°-90° C., and at least when elevated pressure is needed to keep a liquid state in the reaction mixture at the temperature(s) used, the reaction mixture is at such an elevated pressure, whereby ar-bromination occurs. The feeding is conducted at a rate slow enough to form high assay reaction-derived decabromodiphenylethane product, which is an effective flame retardant. | 09-18-2008 |

| 20090233097 | Process Technology For Recovering Brominated Styrenic Polymers From Reaction Mixtures in Which They Are Formed and/or Converting Such Mixtures into Pellets or into Granules or Pastilles - Brominated styrenic polymer is recovered from solution in a vaporizable solvent by converting the solution in a devolatilization extruder into a brominated styrenic polymer melt or flow and a separate vapor phase comprised predominately of vaporizable solvent, recovering the melt or flow from the devolatilization extruder, and allowing or causing the melt or flow to solidify. The solidified brominated styrenic polymer can be subdivided into a powder or pelletized form. Pellets so made have improved hardness and/or crush strength properties along with reduced formation of fines. Brominated anionic styrenic polymer is preferably used in the process. | 09-17-2009 |
