Abstract:
The present invention is directed to processes for making a crosslinked cation exchange polymer comprising a fluoro group and an acid group. The process allows the polymer to be efficiently made on a commercial scale, and the polymers are useful to bind potassium in the gastrointestinal tract of a human or animal subject.
