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.
