| titleOfInvention | Recovery of antimony catalyst residue from bromination reaction |
| abstract | The method of brominating a styrene polymer in an organic solvent in the presence of antimony trihalide so as to produce a reaction mixture containing the brominated styrene polymer in an organic solvent is hydrochloric acid or hydrobromic acid or its It is improved by mixing both with the reaction mixture at least once and extracting the antimony catalyst residue from the reaction mixture as an acidic aqueous phase. Preferably, the catalyst residue is recovered from the acidic aqueous phase, and more preferably at least one of the antimony trihalide catalyst used to produce the brominated styrene polymer by recycling the recovered trihalide catalyst residue.
