Abstract
Provided herein are methods of reducing a residual acrylamide monomer content present in an acrylamide-based polymer emulsion comprising adding a treatment agent to the acrylamide-based polymer emulsion. Further provided herein are methods of preparing an acrylamide-based emulsion polymer comprising polymerizing a mixture comprising acrylamide monomers to form an acrylamide-based polymer emulsion; and adding a treatment agent to the acrylamide-based polymer emulsion.
Claims24
A method of reducing a residual acrylamide monomer content present in an acrylamide-based polymer emulsion comprising adding a treatment agent to the acrylamide-based polymer emulsion, wherein the treatment agent comprises amines, amine salts, thiols, or mixtures thereof, and wherein the treatment agent is added in an amount of about 0.1% to about 10% by weight of the acrylamide-based polymer emulsion.
