Process for reducing the friction loss of turbulent or pulsating aqueous liquids and suspensions by adding 1 to 1000 ppm of linear statistical copolymers of the following general formula 1 as flow accelerators in which X is a cation Na + , K + or NH 4 + and Y is hydrogen or a cation Na + , K + or NH 4 + and in which a, b, c and d represent the proportionate weight ratios of the comonomers in% and a vary from 30 to 98, b from 0 to 20, c from 0 to 25 and d from 0 to 45, however, the sum of the proportions of b and c must be at least 2, which in their preparation while maintaining their water solubility as aqueous , dimensionally stable, cutable jellies. |
