Abstract
Ultra-high molecular weight poly(N-propionylethylenimines) are disclosed that are useful as water purification agents. The polymers of this invention include partially deacylated poly(N-propionylethylenimines) derived from poly(N-propionylethylenimines) having a weight average molecular weight, M.sub.w, between about 1 million and about 20 million. The polymers have a degree of deacylation that ranges from about 10% to about 90%.
