ABSTRACT:
Cationic emulsion polymers useful as thickening agents in aqueous dense brine solutions are disclosed. The cationic polymers are water-in-oil emulsion polymers of acrylamide or methacrylamide and a cationic monomer. The polymers have an intrinsic viscosity in 1.0 N KCl of at least 1 dl/g and preferably have an acrylamide or methacrylamide to cationic monomer molar ratio of about 60:40 to 95:5.
