Process for brominating butadiene polymers using ester solvent mixtures
摘要：
Butadiene copolymers are brominated using certain quaternary ammonium or phosphonium tribromides as the brominating agent. The bromination is performed in solution in a mixture of n-butyl acetate and ethyl acetate. The bromination process proceeds easily under mild conditions, and produces a brominated product that has excellent thermal stability.
摘要（中）：

使用某些季铵或三溴化磷作为溴化剂溴丁二烯共聚物。 溴化反应在乙酸正丁酯和乙酸乙酯的混合溶液中进行。 溴化过程在温和条件下容易进行，并产生具有优异热稳定性的溴化产物。
