Process for the production of high molecular weight copolymers of diallylammonium monomers and acrylamide monomers in an aqueous dispersed phase

摘要

Water-soluble, high molecular weight, linear copolymers of a diallyl ammonium monomer and an acrylamide monomer are prepared by emulsion copolymerization of a major portion of the acrylamide monomer via stage-addition, and the addition of a chain transfer agent at the conclusion of said copolymerization to prevent branching and cross-linking.
