Beschreibung
Zusammenfassung:	A first copolymer in the form of beads of a vinyl sulphonic acid and a polyethylenically unsaturated monomer. Also a second copolymer in the form of beads of a derivative of a vinyl sulphonic acid chemically convertible to the sulphonic acid and a polyethylenically unsaturated monomer. The second copolymer is converted to the first copolymer by hydrolysis, advantageously in the presence of ultrasound.
