The invention relates to processes for the treatment of substrates which comprise applying at least one ammonium salt to the substrate as an algicide, bactericide or fungicide, said ammonium salt containing units which contain diepoxide and diamine radicals.

Quaternary ammonium salts of diepoxides and diamines, their preparation

A cationic adsorption agent which is obtained by reaction of

Cationic adsorption agent

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

Process for the purification of industrial effluents

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.

Polymeric quaternary ammonium salts containing specific cationic

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.

Process for dyeing or printing fibrous material using quaternary

A process for purifying industrial effluents, wherein said effluents are brought into contact with a polymer adsorption material which is in the form of a solvated, preferably hydrated, gel.

Hair-care compositions in the form of aqueous, alcoholic or aqueous alcoholic solutions, creams, gels, emulsions, or of aerosols which optionally contain a propellant are provided which contain at least one polymeric quaternary ammonium salt which contains cationic units of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are the same or different and represent alkyl, cycloalkyl or alkenyl, aryl or aralkyl, or (R.sub.1 and R.sub.2) and/or (R.sub.3 and R.sub.4) together with the nitrogen atom to which they are bonded, form an unsubstituted or substituted heterocyclic ring containing 3 to 6 ring members,

Cosmetic compositions containing polymeric quaternary ammonium salts

Cationically modified, cellulose-containing materials

A polysaccharide-containing adsorbent for the removal of heavy metal ions from an effluent which adsorbent has been manufactured from

Polysaccharide-containing adsorbent

A cellulosic absorption material for the removal of heavy metal ions from fluids, which material contains at least one chelate-forming amino acid group which is bonded through the group of the formula ##STR1## to the cellulose portion wherein the carbonyl group is linked to the chelate-forming radical and the oxygen is linked to the cellulose portion.

Ionically modified cellulose materials for removal of heavy metal ions

A novel process for purifying industrial effluents which comprises bringing said effluents into contact with cellulosic absorbent which has been pretreated with precipitants.

A process for the purification of industrial effluents which comprises bringing said effluents into contact with an adsorption material which contains a carrier that is pretreated with a precipitate of a basic nitrogenous polymeric compound with an activated clay mineral.
