| 摘 要： | 简述在二氯乙烷溶剂中，以路易斯酸三氯化铝为催化剂，在近似无水条件下，聚苯乙烯与氯化溴反应制备溴化聚苯乙烯的方法。讨论了工艺参数，如催化剂用量、反应温度、反应时间等的改变对产物结构性能，如分子链的断裂和玻璃化温度的转变的作用规律。从而明确了工艺条件对聚苯乙烯溴化过程的影响。

| Abstract: | A method was investigated for preparing brominated polystyrene by the interaction between low molecular polystyrene and bromine chloride in 1,2-dichloroethane in the presence of AlCl3 and under almost anhydrous condition.The influence on the structure properties of BPS,e.g.the break of the molecular chain and change of T g value,was also studied by changing the technological parameters,such as the amount of catalyst,reaction temperature and time.Finally,the technological conditions affecting the brominated process of BPS were determined. |
