Abstract (en)
[origin: DE10105103A1] The invention relates to spherical shaped copolymers produced by means of a seed-supply method with a supply of vinyl aromatic, divinylbenzol, methylacrylate and radical starters, which can be transformed into gel-type cation exchangers with a high stability and purity by sulfonation without the need for a swelling agent.
