    • Acid block anionic selective polymeric membranes are provided of the type having a woven or non-woven cloth reinforcing structure. The polymer of the membrane is prepared by the process comprising copolymerizing components I, II, and III wherein I is an ethylenically unsaturated aliphatic or aromatic tertiary or quaternary amine monomer. II is a cross-linking monomer, and III is vinylbenzyl chloride. The reaction is conducted in the presence of a free radical polymerization initiator. Additionally, anionic exchange membranes of the type used in electrodialysis apparatus are disclosed and comprise a woven or nonwoven cloth that is impregnated with a copolymer comprising the reaction products of components I, II, and III.
    • 提供了具有织造或非织造布加强结构的类型的酸嵌段阴离子选择性聚合物膜。 膜的聚合物通过包括共聚组分I,II和III的方法制备,其中I是烯属不饱和的脂族或芳族叔胺或季胺单体。 II是交联单体,III是乙烯基苄基氯。 反应在自由基聚合引发剂的存在下进行。 此外,公开了用于电渗析装置中的类型的阴离子交换膜,并且包括浸渍有包含组分I,II和III的反应产物的共聚物的机织或非织造布。
