process for the production of copolymers of high molecular weight diallyldimethylammoniumchlorid and acrylamide in an aqueous dispersed phase.

摘要

Water-soluble, high molecular weight, linear copolymers of diallyl dimethyl ammonium chloride and acrylamide, 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.
