Abstract
A resinous copolymer polyelectrolyte product is produced by a process for addition polymerization of reactants having from about 0.0005 to 0.0050 neutralization equivalents of ionizable monomer per gram. The aqueous reaction mixture for polymerization contains both a cosolvent in proportions low enough to avoid formation of a solution of the polyelectrolyte in the final aqueous medium and an ionizing agent sufficient to ionize at least about 0.0001 neutralization equivalent of said ionizable monomer. The polyelectrolyte has a mean weight average not substantially in excess of 100,000 molecular weight.
