    摘要: Disclosed herein is an inverse emulsion polymer composition comprising a copolymer or copolymer salt of N,N,-dimethylacrylamide and 2-acrylamido-2-methylpropane sulfonic acid or acid salts thereof, having a Brookfield viscosity of less than 20,000 Cps at 23° C. and an active polymer concentration of about 25 to about 75 weight percent. The inverse emulsion polymer composition is in a hydrocarbon with a primary surfactant and optionally contains water.
