Abstract
Water soluable, aqueous salt solution dispersible polymers and aqueous salt solutions containing dispersed polymers are produced by polymerization of ethylenically unsaturated soluble monomers in an aqueous salt solution in the presence of at least one carbohydrate. The polymers and aqueous salt solutions containing the dispersed polymers are useful for paper making, water clarification and emulsion breaking.
