Procedure
A water-soluble relative permeability modifier of the present invention was made as follows. First, a polymer was made by mixing 45.0 g of dimethylaminoethyl methacrylate, 6.8 g acrylic acid, 372.0 g of water and sparging with nitrogen for 30 minutes. Thereafter, the pH was adjusted to approximately 5.3 with 5.7 mL of concentrated sulfuric acid, followed by the addition of 0.2 mL of 2-mercaptoethanol and 1.3 g of 2,2′-azo bis(2-amidinopropane)dihydrochloride. The resulting solution was then heated to 71° C., with stirring, and held for 18 hours to produce poly(dimethylaminoethyl methacrylate/acrylic acid).
