| titleOfInvention | Cationic polymer dispersions, method of producing said dispersions and use therof |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to water-in-water cationic polymer dispersions. A water-in-water polymer dispersion is described, containing cationic polymer A and at least one dispersant B, characterised by that, the said polymer A is formed from: a1) 1 to 60 wt % of cationic monomers of the type of cationised dialkylaminoalkyl (meth)acrylates and a2) 40 to 99 wt % of nonionic monomers, and that said polymeric cationic dispersant B is formed from 100 wt % of cationised dialkylaminoalkyl(meth)acrylamides and has average molecular weight M w from 75000 to 350000 g/mol. Also described is a method of producing said water-in-water polymer dispersions from cationic polymer A and at least one polymeric cationic dispersant B, characterised by that, in the polymerisation reactor, aqueous solution of the polymeric cationic dispersant B with average molecular weight from 75000 to 350000 g/mol is synthesised from 100 wt % cationised dialkylaminoalkyl(meth)acrylamides, and a monomer mixture a1) 1 to 60 wt % cationised dialkylaminoalkyl (meth)acrylates and a2) 40 to 99 wt % of nonionic monomers, which are combined, with addition of free-radical initiators, and free-radical polymerisation of the monomer mixture is carried out. Also described is use of said water-in-water polymer dispersion as a flocculant in precipitation of solids, preferably in water and treatment of water or waste water purification, in extraction of raw materials, preferably coal, aluminium or petroleum, or as demulsifier in the separation of aqueous mixtures containing oil and/or fat, as a preservative and dehydrating agent in paper production, as thickener, as well as an additive in phytosantitary reagent, optionally together with other biologically active substances as an additive in anti-erosion reagent. n EFFECT: avoiding rheological problems during production of said polymer dispersion, high stability of polymer dispersion with respect to its rheological behaviour during storage. n 27 cl, 12 tbl, 18 ex |
