ABSTRACT:
Novel ionene polymers are formed by the mannich reaction of an aromatic molecule having an electron withdrawing group with a lower aliphatic aldehyde and a lower aliphatic secondary amine followed by polymerizing the manniched derivative by the use of chain extenders from the group of di-functional condensation monomers consisting of alkyl dihalides, epihalohydrins and 1,4-dihalobutene-2. Additionally, the polymers may be prepared by substituting some or all of the secondary amines above with a primary amine, and quaternizing the resultant polymers formed.
The product of this invention have present utility as polymers useful for water clarification and as emulsion breakers for water-in-oil or oil-in-water emulsions.
