PROCESS FOR BROMINATING BUTADIENE/VINYL AROMATIC COPOLYMERS
摘要
<p>A polybutadiene brominating method uses a quaternary ammonium tribromide as the brominating agent. The brominating is performed in solution, and dual extractions recover the spent brominating agent and recombine it with fresh bromine to regenerate an active tribromide. Solvent and aqueous extraction streams can be purified and recycled as needed.</p>
