Abstract: Process for reducing the friction pressure drop of aqueous liquids and suspensions in turbulent or pulsating flow by adding from 1 to 1,000 ppm of linear random copolymers of the following formula I as drag reducing agents +TR in which X is a Na+, K+ or NH4+ cation and Y is hydrogen or a Na+, K+ or NH4+ cation, and in which a, b, c and d represent the proportional weight ratios of the comonomers in % and a is in the range of from 30 to 98, b from 0 to 20, c from 0 to 25 and d from 0 to 45, however, wherein the sum of the portions of b and c must be at least 2, the said copolymers being obtained in the manufacturing process in the form of aqueous and dimensionally stable jellies capable of being cut, while retaining their solubility in water.
