Abstract: The present disclosure is directed to a process of separating oil from oil-containing wastewater which comprises treating the wastewater with a water-soluble cationic polymer obtained by the polymerization of an epihalohydrin with an alkylene polyamine having the formula ##STR1## wherein R is a lower alkylene having from 2 to about 6 carbon atoms, and R.sub.1 and R.sub.2 are each a lower alkyl of from 1 to about 6 carbon atoms.

Abstract: The present disclosure is directed to novel water-soluble cationic polymers and their use either alone or in conjunction with coagulant aids to flocculate or coagulate matter suspended in aqueous systems. The novel polymer is prepared by reacting an alkylene polyamine with an epihalohydrin under specific conditions which include the incremental reaction of the epihalohydrin to fully react with the epihalohydrin and attain a polymer of uniform viscosity.
