Abstract
Unsheared, water-soluble, branched, high molecular weight, anionic, polymeric flocculants are produced by polymerizing ethylenically unsaturated anionic, and optionally 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.
