Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA) is a homopolymer of diallyldimethylammonium chloride (DADMAC). The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products. PolyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationic polymer. The charge density makes it well suited for flocculation.

生产方法
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.广泛应用于水处理行业,该共聚物是极好的阳离子有机高分子絮凝剂。它的电荷密度范围大,阳离子单体占共聚物的摩尔分数从10%到58%,并且分子量也都很高。它既可起电荷的中和作用,又可起桥联絮凝作用。
