ABSTRACT:
The invention comprises the manufacture of cation exchangers by the copolymerization of a sulfonic acid with two other monomers such as acrylamide and n-methylolacrylamide which react simultaneously with the polymerization to form a cross-linking unit. The non-polymerizing (NP) solvent employed is water.
