Abstract:
A polymer mixture in solid or aqueous form includes a content of from 5 to 95% by weight of a first polymer and a content of from 5 to 95% by weight of a second polymer. The first polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 20 000 g/mol. The second polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 50 000 g/mol. The polymer mixture can inhibit precipitation and sedimentation of calcium salts and magnesium salts in water-bearing systems.
