FIELD: chemistry.
SUBSTANCE: invention relates to a method of preparing concentrated solutions of polymers from polymer granules and can be used particularly in waste water treatment, as well as in making paper and transportation of tertiary oil. Water and polymer particles are combined in a dispersing unit. The particles are dispersed in water by using a first power level per cubic metre. After coming out of the said dispersing unit, the mixture of water and particles is fed into a reservoir, where it is dissolved while stirring. At the end of its dwell time in the reservoir, the aqueous solution of polymer undergoes second dispersion while stirring in the dispersing unit at a power level per cubic metre lower than that used in the first case.
EFFECT: possibility of obtaining solutions in a wide concentration range without formation of agglomerates with less power consumption.
