PROBLEM TO BE SOLVED: To provide methods of removing potassium in the gastrointestinal tract.SOLUTION: The present invention is directed to crosslinked cation exchange polymers comprising a fluoro group and an acid group, pharmaceutical compositions of these polymers, compositions of a linear polyol and salts of such polymers. Crosslinked cation exchange polymers having beneficial physical properties, including combinations of the particle size, particle shape, particle size distribution, viscosity, yield stress, compressibility, surface morphology, and/or swelling ratio are also described. These polymers and compositions are useful to bind potassium in the gastrointestinal tract.SELECTED DRAWING: None |
