溴化聚苯乙烯(简称BPS)是一种溴系有机阻燃剂，具有高阻燃性、热稳定性及光稳定性等良好的机械物理和化学性质，广泛应用于聚对苯二甲酸丁二醇酯、聚对苯二甲酸乙本醇酯、聚苯醚、尼龙-66等工程塑料。
该聚苯乙烯与烷基卤化物、烷基卤化铝、脱水剂混合，用溴素溴化得到窄分布低分子量溴化聚苯乙烯。
The polystyrene is mixed with alkyl halide, alkyl aluminium halide, dehydrant, brominated by bromine to get narrow distributed brominated polystyrene with low molecular weight.
以氯化溴和聚苯乙烯为原料，以三氯化锑为催化剂，对合成阻燃剂溴化聚苯乙烯的工艺条件进行了试验研究。
The optimal parameters of synthesizing brominated polystyrene(BPS) was determined in the presence of antimony chloride as a Lewis acid, bromine chloride and polystyrene as raw materials.
