Abstract: A process for making down a powder is provided. The process comprises making down a powder comprising one or more acrylamide-based polymer(s) to form a made down powder solution, comprising blending a mixture of the powder and a solvent for no more than about 15 minutes to yield the made down powder solution, wherein the powder comprises particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns.

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.

Abstract: A method of making acrylamide-acrylic acid copolymers in water-in-oil latices is described. The method results in a copolymer having randomly distributed carboxylate functionalities and is suitable for ionic crosslinking. The copolymers and their ionically crosslinked counterparts are useful for enhanced oil recovery processes.
