Abstract: Highly polymerized quaternary ammonium compounds are produced by quaternizing condensation products of acrylamide or methacrylamide with formaldehyde and secondary amines having the general formula in which R represents hydrogen or methyl and R1 and R2 represent aliphatic, cycloaliphatic, araliphatic or aromatic radicals, which may be identical or different, which may bear further substituents or may be combined to form a ring system and copolymerizing the products with other ethylenically unsaturated polymerizable compounds in the presence of conventional polymerization catalysts in organic solvents in which the monomers are soluble and the copolymers are insoluble and are precipitated during the polymerization, the process differing from that of the parent Specification only in that tertiary butanol is used as solvent.
