Abstract
This invention relates to the preparation of sulfonated copolymers having a particle size in the range of 10 to 5,000 .mu.m by a suspension copolymerization process, wherein an unsulfonated monomer is copolymerized with a sulfonated monomer such as the trioctylammonium salt of vinyl sulfonate monomer or the trioctylammonium salt of acrylamedomethylpropane sulfonate.
