ABSTRACT This invention relates to a water soluble quaternized epihalohydrin copolymer. The copolymer is prepared by first reacting an epihalohydrin with a polyepoxide in an organic solvent in the presence of a polymerization catalyst. The copolymer thus produced is then quaternized by reacting it with tertiary amine. The quaternized epihalohydrin co- polymer is useful in removing suspended solids from aqueous dispersions. It is particularly useful in processes for clarifying raw water.
