ABSTRACT:
Novel ionene polymers are formed by the Mannich reaction of an aromatic molcule 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 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 to increase the molecular weight of the product.
The products of this invention have utility as polymers useful for water clarification and as emulsion breakers for water-in-oil or oil-in-water emulsions.
These polymers and their quaternary salts have also a special utility here as an electroconductive coating which, when applied to paper specially as a substrate, produce an electroconductive surface adapted for electrographic printing.
In the group above specially preferred polymers are those prepared from tris(dialkylaminomethyl)phenol and a chain extender such as 1,4-dichlorobutene-2 (DCB) or epichlorohydrin and a bismethylchloride quaternary of tris(dialkylaminomethyl)phenol with the same chain extenders and their particular use as conductive resins or polymers. A preferred polymer in this group is from tris(dimethylaminomethyl)phenol. Obvious equivalents of bismethylchloride quaternaries are quaternaries prepared from other lower alkyl halides such as ethyl, propyl, and butyl where the carbon chain length is C.sub.1 -C.sub.6.
