Abstract: Aqueous dispersions of modified copolymers are obtained by reacting, at a pH value between 3 and 11 and at temperatures of 10 DEG to 70 DEG C., 1,2-epoxy-3-chloropropane with an aqueous dispersion of a copolymer prepared from at least one a -ethylenically unsaturated carboxylic acid (I) and at least one other ethylenically unsaturated compound (II) which is copolymerizable therewith, the molar ratio of 1,2-epoxy-3-chloropropane to the total carboxyl groups in the copolymer being 1:1 or less than 1:1. Acid monomers (I) specified are acrylic, methacrylic, maleic and fumaric acids and mixtures thereof. Comonomer (II) specified are esters of acrylic and methacrylic acid with alkanols having one to eight carbon atoms, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, N - (hydroxymethyl) - acrylamide, N - (hydroxymethyl) - methacrylamide, N - (2 - oxahexyl) - acrylamide, N - (2-oxahexyl)-methacrylamide, vinyl acetate, vinyl propionate, vinyl butyrate, styrene, a -methylstyrene, o-, m- and p-methylstyrene, butadiene, vinyl butyl ether, vinyl chloride and vinylidene chloride. The modified copolymer dispersions can be crosslinked with basic compounds, e.g. sodium and/or potassium hydroxide, even at room temperature, and may be used for adhesives, coatings and impregnations for textiles.

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.
