<p>Water-soluble, high molecular weight, linear copolymers of diallyl dimethyl ammonium chloride and acrylamide of various cationicities are prepared by copolymerization of a major portion of the acrylamide monomer via stage-addition in a solvent solution and adding a chain transfer agent at the conclusion of said copolymerization to prevent branching and crosslinking from occurring.</p> |
