Abstract

A pumpable water-in-oil emulsion with high solid content in a disperse aq. phase, contg. a water-soluble high M.W. anionic polyacrylamide is obtd. by (1) producing a water-in-oil emulsion from an acrylamide monomer dissolved in water as the disperse phase and a liq. hydrocarbon as the continuous phase, the amt. of acrylamide in the aq. phase being 15-65wt.%, and the amt. of hydrocarbon w.r.t. wt. of aq. phase being 15-100wt.%, and the emulsion contg. as emulsive an effective amt. of a non-ionic or anionic surface active agent, (2) polymg. the acrylamide to form a water-soluble high MW polyacrylamide in the disperse aq. phase; (3) distributing uniformly in the emulsion an aq. strong alkali in amts. of 0.5-50 mol.per 100 mol. acrylamide units and (4) hydrolysing the polyacrylamide to form the corresp. anionic polyacrylamide. The method is simple, requiring no special appts. and is rapid flexible and economic. The emulsion can be pumped at a polymer solid content of 20-50% and can be made practically completely storage stable.
