Abstract: The present invention is directed towards a composition comprising(A) at least one polymer comprising (a) a backbone that bears one to forty β-aminoalcohol groups or β-amino-(alkylenoxide) groups (b) wherein some β-aminoalcohol groups or β-amino-(alkylenoxide) groups are esterified with a mono- or diacid of a polyalkylene oxide of which at least 50 mol-% of the alkylene oxide groups are ethylene oxide groups, or with the monomethyl ether of a monoacid of a polyalkylene oxide of which at least 50 mol-% of the alkylene oxide groups are eth-ylene oxide groups, and, optionally,(c) of which some β-aminoalcohol groups or β-amino-(alkylenoxide) groups are esterified with aliphatic C4-C10-di- or tricarboxylic acid.
