Reacting weakly basic anion exchangers bearing tertiary amino groups with ethylene oxide under pH control and addition of acid leads to superior strongly basic anion exchangers.

Process for the preparation of strongly basic anion exchangers using ethylene oxide

Process for preparing selective ion exchangers

Polymers of improved surface quality are obtained by polymerization of microencapsulated monomer droplets suspended in an aqueous phase if the monomer and/or the aqueous phase contain a polymerization inhibitor.

Process for the preparation of microencapsulated polymers

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 &lt;7% by weight and the mixture remaining after this distillative dewatering is subjected to aminolysis in the customary manner.
