| Number | Title | Issue Date |
| 8350074 | Low triphenylphosphate, high phosphorous content isopropyl phenyl phosphates with high ortho alkylation The present invention relates to low triphenyl phosphate, high phosphorous content aryl phosphates with high ortho alkylation that are suitable for use as flame retardant compositions, processes for their preparation, and their use as flame retardants. ... | 01/08/2013 |
| 8344171 | Process for making dihydrocarbyl hydrocarbonphosphonates This invention provides a process for the preparation of a dihydrocarbyl hydrocarbonphosphonate. The process comprises forming a reaction mixture from components comprising (i) at least one dihydrocarbyl phosphite, (ii) at least one alkali metal hydrocarbyloxide, an... | 01/01/2013 |
| 8273831 | 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, recov... | 09/25/2012 |
| 8217207 | 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 reac... | 07/10/2012 |
| 8143433 | Low triphenylphosphate, high phosphorous content isopropyl phenyl phosphates with high ortho alkylation The present invention relates to low triphenyl phosphate, high phosphorous content aryl phosphates with high ortho alkylation that are suitable for use as flame retardant compositions, processes for their preparation, and their use as flame retardants. ... | 03/27/2012 |
| 8034986 | Processing of solid brominated aromatic organic compounds containing occluded bromine Solid-state highly brominated compounds such as solid brominated flame retardants with bromine contents of at least about 60 wt % often contain occluded bromine. Because of their high bromine contents, such compounds have relatively low solubility in common organic ... | 10/11/2011 |
| 7994373 | 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 reac... | 08/09/2011 |
