The invention relates to a copolymer whose overall structure as such and/or an optionally present segment A having at least 10 bivalent structural units in the overall structure contains surface-active bivalent structural units present in the form of long hydrocarbon chains among other forms. The copolymer is effective as a universal surface-active additive, especially also in conjunction with nonpolar media.
