Abstract
Abstract Water-soluble or water-dispersible graft polymers comprising at least 20% by weight, based on said graft polymer, of a hydrophilic graft constituent bonded to a carbon atom and at least one hydrophobic radical which is bonded to the graft constituent via a polyglycol ether chain, the polyglycol ether chain containing 2 to 200 ##STR1## groups. These graft polymers can be used individually, as mixtures or in combination with other active substances as, for example, antifoams, antistatic agents, builders, emulsifiers, padding assistants, wetting agents, paper deaerators, sludge dewatering assistants, textile assistants, greying inhibitors or detergents.
