    • According to the process according to the invention for the preparation of anion exchange resins of the poly(meth)acrylamide type by aminolysis of bead polymers of cross-linked poly(meth)acrylic acid esters with excess polyamine, subsequent separation of the anion exchange resins from the liquid phase containing the unreacted polyamine, washing the anion exchangers free of amine with water and recovering the polyamines from the washing waters, the liquid phase containing the unreacted polyamine and the polyamine-containing washing waters are immediately mixed with the bead polymer of cross-linked poly(meth)acrylic acid ester to be subjected to aminolysis, the amount of fresh polyamine necessary for the establishment of the desired polyamine excess is added to the mixture, the mixture thus obtained is distillatively dewatered until its water content has fallen to a value of
    • 根据本发明的制备聚(甲基)丙烯酰胺型阴离子交换树脂的方法,通过交联聚(甲基)丙烯酸酯与多余多胺的珠粒聚合物的分解,随后分离阴离子交换树脂 从含有未反应的多胺的液相中,用水洗涤不含胺的阴离子交换剂并从洗涤水中回收多胺,将含有未反应的多胺和含多胺洗涤水的液相立即与交叉的珠聚合物 连接的聚(甲基)丙烯酸酯进行氨解,将所需多胺过量所需的新鲜多胺的量加入混合物中,将得到的混合物进行蒸馏脱水,直到其含水量降至 值为<7重量%,并且在该蒸馏脱水后残留的混合物在该溶液中进行氨解 玛丽的样子
