Abstract
Cationic, water-soluble, amine-epichlorohydrin polymeric compositions formed by reacting polymeric bis(3-chloro-2-hydroxypropyl) amines with tertiary amines are useful in papermaking processes, in water purification processes, textile manufacturing processes, and for the control of pests such as algae, bacteria and fungi.
