Abstract: Highly random acrylamide-acrylic acid copolymers are described. Ionic crosslinking of the highly random copolymers in dilute solution results in improved viscosity and gel strength compared to copolymers prepared by conventional methods. The ionically crosslinked copolymers are useful in enhanced oil recovery processes.

Abstract: A solution including an associative polymer, a cyclodextrin polymer, and a solvent is provided. The associative polymer is a powder in the absence of the solvent. Additionally, a method of making down an associative polymer powder to form a solution is provided. The method includes blending a mixture of the powder, a cyclodextrin polymer, and a solvent to yield the solution, wherein the powder includes particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns. Additionally, a powder product is provided. The powder product includes from about 80 wt. % to about 99.9 wt. % associative polymer; and from about 0.1 wt. % to about 20 wt. % of a cyclodextrin polymer.

Abstract: A system for continuously making-down a dry powder material is provided. The system may include a liquid supply system, a material feed system, a vessel, a filter, and an agitator. The vessel may receive a continuous supply of liquid from the liquid supply system and a continuous supply of dry powder from the material feed system. The liquid and material may be discharged continuously from the vessel. A filter may sealingly extend across the outlet to filter the solution exiting the vessel. The filter may include an upstream surface in contact with the inner volume of the vessel. The agitator may be disposed within the vessel and may be configured to agitate the contents of the vessel. The agitator may include a wiping member configured to contact the upstream surface of the filter while agitating the contents.
