聚二甲基二烯丙基氯化铵制备

一般情况下，聚二烯丙基二甲基氯化铵有两种结构。一种是六元环，另一种是五元环。实际五元环结构更为普遍。五元环的聚二烯丙基二甲基氯化铵的相对分子质量在4×104～3×106范围内，用途更大。其反应式如下：

(1)原料提纯　由于所用氯丙烯因生产时有未除尽的一些副产品如烯丙醇、烯丙基醚以及一些无机杂质如Fe3+等，这些杂质在聚合时会起阻聚作用，因此必须除去。水洗后蒸馏，因为生成叔胺后还得经过酸、碱处理，这就可将氯丙烯带入的大部分杂质及反应中的水溶性副产品除去，生成的叔胺先干燥后蒸馏，取55～57℃馏分，由此又可将不溶于水的副产物除去，最后得到较纯的烯丙基叔胺。这样可减少操作单元，原料损耗，从而节省原料，提高了反应的总收率，即使得聚二烯丙基二甲基氯化铵的收率可达90%以上。

(2)单体结晶　由于二烯丙基二甲基氯化铵在极性溶剂中的溶解度很大，在非极性溶剂中的溶解度极小，且溶解度随温度的影响不大，这就决定了二烯丙基二甲基氯化铵很难在某一种或几种溶剂中重结晶。可采用在非极性溶剂丙酮中缓慢反应，在足量丙酮中反应可得到晶形很好的二烯丙基二甲基氯化铵晶体，然后减压过滤，用丙酮洗涤数遍再干燥既得纯净的无色二烯丙基二甲基氯化铵晶体。
(3)聚合　采用水溶液聚合，作为絮凝剂，其分子量越大越好，分子链越长越好。可选用硫酸亚铁过氧化氢引发系统，加入EDTA的二钠盐，氮气保护并抽真空下聚合，以水为溶剂。
