Abstract: A novel process for the purification of industrial effluents, wherein the effluents are brought into contact with cationically modified, cellulose-containing materials, the cationic constituent of which is bonded to the cellulose part via the grouping of the general formula--O--CH.sub.2 --N<in which the nitrogen belongs to an amide group of the cationic constituent and the oxygen is bonded to the cellulose part.

Abstract: Disclosed are novel polymeric quaternary ammonium salts containing specific di-tertiary amino substituted cationic recurring units. Said salts are useful as dyeing and finishing agents, especially for dyeing textile materials, such as polyacrylonitrile fiber materials, as dispersing agents and emulsifiers, as antistatic, antimicrobial and flocculating agents and as precipitants.

Abstract: A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
