一种卤代聚苯乙烯海因的合成方法

本发明公开了一种卤代聚苯乙烯海因的合成方法，通过通过一步合成法；通过先制备合成卤代聚苯乙烯海因的原料，用5，5‑二甲基海因在碱性条件下与卤素合成1‑卤‑5，5‑二甲基海因；采用氯甲基聚苯乙烯与单卤二甲基海因一步合成卤代聚苯乙烯海因，即1‑卤‑3‑（4‑聚苯乙烯‑苄基）‑5，5‑二甲基海因，合成效率高，成本低，利于大规模生产。同时通过在溶剂中合成卤代聚苯乙烯海因，有利于聚苯乙烯的溶胀，有利于提高收率，反应时间短，合成效率高，有利于大幅度降低成本。将母液循环套用，制备时的母液中含有大量材料，避免废液排放，减少废水处理成本；并且变废为宝，以降低成本可以循环套用数次，减少废水产生量，进一步降低废水处理成本和生产成本。
