Hydrophilic high polymers prepared from aqueous solutions or dispersions of polyoxypropylene polyamine N-N'-polymethylene sulfonates

Abstract

A self curing aqueous solution/dispersion comprising about 50-70 wt. % water, about 25-35 wt. % of a novel N-polymethylene substituted polyoxypropylene polyamine and about 3-9 wt. % of a curable polymer-forming component such as an epoxy-resin is described. The solution is useful for injection into permeable earth formations such as unconsolidated sands to reduce their permeability and consolidate the formation. Novel N-substituted polyamines of the formula [NaO.sub.3 S--R.sub.1 ].sub.m A wherein R.sub.1 is a C.sub.2 to C.sub.6 polymethylene group and A is a polyoxyalkylene polyamine are employed in the solution to render the epoxy-resin component adequately soluble or dispersible in the aqueous solution and to act as the curing agent for the resin.
