Abstract

The invention comprises water-soluble polymers containing in an interpolymerized form a polyethylene polyamine having an average molecular weight of 400 to 1200, a propylene glycol/epihalohydrin adduct containing at least 4 mole proportions of epihalohydrin for each mole proportion of propylene glycol, and ethyleneimine in a proportion at least equal to the sum of weights of polyethylene polyamine and propylene glycol/epihalohydrin adduct. Specified epihalohydrins are epichlorohydrin, epibromohydrin and mixtures thereof.
