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 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.
