摘要：
FIELD: chemistry.SUBSTANCE: present invention relates to a method of producing polymers by radical precipitation polymerisation: a) 99.99-10 wt % of at least one α,β-ethylenically unsaturated compound with at least one cationogenic and/or cationic group in the molecule, wherein a) is selected from vinyl imidazoles of general formula (III) in which residues R1-R3 denote hydrogen, an alkyl with 1-4 carbon atoms or a phenyl, b) from 0 to less than 25 wt % of at least one monoethylenically unsaturated compound, different from component a) and having amide groups, which is selected from a group comprising amide group-containing α,β-ethylenically unsaturated compounds of general formula (IV): in which R2 denotes a group of formula CH2=CH-, and R1 and R3 together with an amide group with which they are bonded form a lactam with 5 ring atoms, c) 0.01-5 wt % of a cross-linking agent, d) 0-15 wt % of at least one monoethylenically unsaturated compound selected from alkyl(meth)acrylates with 12-30 carbon atoms in the alkyl, e) 0-30 wt % methyl methacrylate, under the condition that the total amount of components a) - e) is equal to 100 wt %, characterised by that realisation thereof involves use of at least two different water-insoluble initiators A and B, which are selected such that the breakdown temperature of each is at least 70°C and said temperature values differ from each other by at least 10°C. Also described is use of at least one polymer obtained using said method to modify rheology of aqueous, alcohol or water-alcohol compositions. Described also is a cosmetic or pharmaceutical agent which contains at least one polymer obtained using said method.EFFECT: obtaining polymers having optimum consumer properties and a thickening effect at the same time.12 cl, 1 tbl, 16 exНастоящее изобретение относится к способу получения полимеров осадительной радикальной полимеризацией: а) от 99,99 до 10% масс. по меньшей мере одного α,β-этилен-ненасыщенного соединения по меньшей ме
