| titleOfInvention | Water-soluble polymer dispersion and method of obtaining water-soluble polimer dispersion |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to water-soluble polymer dispersion and method of its obtaining, its application, method of paper production from water suspension. Dispersion includes following components: dispersed polymer, consisting of water-soluble monomer A and water-soluble cationic monomer B, at least one polymeric stabiliser C in amount approximately from 0.05 to approximately 10% wt and co-stabiliser D cationic polyelectrolyte in amount approximately from 1 to approximately 25% wt relative to total dispersion weight. In polymer dispersion there are no essential amounts of salts of inorganic multivalent anion. Dispersed polymer consists of: a) approximately from 50 to approximately 99% molar monomer A, which represents compound of general formula I , where R 1 =H or methyl, R 2 =H, methyl, ethyl, isopropyl, metiloil, hydroxyethyl or 2-hydroxypropyl, and b) approximately from 1 to approximately 50% molar monomer B, representing compound of general formula II , where R 1 = H or methyl, R 3 , R 4 , R 5 - independently on each other H, alkyl(C 1 -C 8 ), benzyl or alkylbenzyl , A=NH, O, B=alkyl(C 1 -C 10 ) or hydroxyalkyl(C 1 -C 10 ), X - =anionic counter-ion. Polymer stabiliser C represents copolymer, which contains at least, one monomer, selected from group, including diallyldimethylammonium chloride (DADMAC), vinylpyridonium chloride, N-vinylimidazoline chloride, vinylbenzyltrimethylammonium chloride and their mixture, and/or compound of general formula II and one of compounds of general formula III, IV and V. Compound of general formula III represents polyether with one functional end allyl group , where R 1 =H or methyl, R 6 = independently on each other H, methyl or ethyl, n=1 or 3, x = from 5 to 50 and y = from 5 to 50. Compound of general formula IV is macroinitiator , where R 1 =H or methyl, R 6 = independently on each other H, methyl or ethyl, R 7 , R 8 = independently on each other alkyl, cyanoalkyl, carbalcoxyalkyl, (C 1 -C 8 ), n=1 or 3 and x = from 5 to 100. Compound of general formula V represents polyether with one functional end vinyl group , where R 1 =H or methyl, R 6 =H, methyl or ethyl, n = 1 or 3 and x = from 5 to 50. Weight ratio of stabilisers and co-stabilisers to dispersed polymer is C+D/ A+B<1. Method of obtaining dispersion is in polymerisation of said above components in one stage. Dispersion is used as additive for improvement of retention in production of paper, as thickener and/or as additive for improvement of dirt-repellent properties. Method of paper production from water suspension, which contains cellulose fibres and non-obligatory fillers, lies in addition to suspension of said above water-soluble polymer dispersion. Then forming is carried out and suspension is dried on net. n EFFECT: obtaining water-soluble polymer dispersion with low viscosity and high molecular weight, increase of serviceable life in storage. n 23 cl, 3 tbl, 25 ex |
