1. A process for making an acrylamide-based polymer solution, comprising blending a mixture of an acrylamide-based polymer powder and a solvent for no more than about 15 minutes to yield the polymer solution,
wherein the acrylamide-based polymer powder comprises particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns, wherein the acrylamide-based polymer comprises formula AP1:
wherein E is one or more associative monomer units(s), F is one or more additional monomer unit(s), G is one or more additional monomer unit(s) of Formula I:
wherein R1 is H or C1-C4 alkyl and each R2 is independently H or an alkyl group, an aryl group, a fluoroalkyl group, or a fluoroaryl group, and H is optionally present and is one or more piperidine-2,6-dione unit(s),
wherein the one or more piperidine-2,6-dione(s) are formed upon cyclization of an acrylamide nitrogen of the additional monomer unit of Formula I (“G”) on a carbonyl of the additional monomer unit (“F”).
