FIELD: chemistry of polymers. SUBSTANCE: proposed dispersion comprises continued phase of oil and emulsifier together with discrete phase of aqueous solution of hydroxamate polymer (its molecular weight being about 3000). Said microdispersion is stable, its pH being more 7. Continued phase of hydrocarbon oil and emulsifier and discrete phase being aqueous solution of polymer represent emulsion water-in-oil which is used as reagent 1. Neutralized hydroxyl amine and excess amount of the base are used as reagent 2. pH of said microdispersion is brought to value being more than 7. EFFECT: improved quality of desired product and efficiency of the method. 9 cl, 3 tbl
