Abstract
Water-soluble, branched, high molecular weight, cationic and non-ionic polymeric flocculants capable of manifesting their full performance potential without shearing are produced by polymerizing ethylenically unsaturated cationic and non-ionic monomers and a branching agent in the presence of a chain-transfer agent. They are useful as flocculating agents for releasing water from dispersions of suspended solids.
