    • Water-soluble poly(quaternary ammonium) polyether polyelectrolyte salts containing quaternary nitrogen atoms in the polymer backbone and chain-extended by ether groups are prepared by treating the polymeric reaction product from an N,N,N'',N''tetraalkyl-hydroxy substituted diamine and an organic dihalide such as a dihaloalkane or a dihalo ether with an epoxyhaloalkane. These polyelectrolytes are used in processes for flocculating particles dispersed in aqueous media, for example, white water clarification, clay flocculation, sewage treatment, and wet-end addition, by adding the polyelectrolyte to the aqueous media in amounts sufficient to flocculate the dispersed particles.
    • 通过将N,N,N',N'-四烷基 - 羟基取代的聚合反应产物进行处理,制备在聚合物骨架中含有季氮原子并由醚基延伸的水溶性聚(季铵)聚电解质聚电解质盐 二胺和有机二卤化物如二卤代烷烃或二卤代醚与环氧卤代烷烃。 这些聚电解质用于通过以足以使分散的颗粒絮凝的量将聚电解质加入到水性介质中来絮凝分散在水性介质中的颗粒的方法,例如白水澄清,粘土絮凝,污水处理和湿法添加。
