    Abstract: The invention concerns pyrrolidone-group-containing polyesters and polyamides of the formulae (I) to (III) in which R is hydrogen or C1-C4 alkyl, whereby two R groups may be bound to each other to form a six-membered ring, X is oxygen or an -NR- group, A is C1-C20 alkylene, which may include in the carbon chain one or more non-adjacent oxygen atoms, sulphur atoms or -NR- groups (in which the N-atom may be protonated or quaternarized), -CO-, -CO-O, -CO-NR, -SO- or -SO2- and may carry additional -COOH or -SO3H functional groups, C6-C20 cycloalkylene, C6-C20 arylene, or a mixture of such groups; Z is a group of the formula (IV) in which B is C1-C20 alkylene, which may include in the carbon chain one or more non-adjacent oxygen atoms, sulphur atoms or -NR-groups (in which the N-atom may be protonated or quaternarized), -CO-, -CO-O-, -CO-NR, -SO- or -SO2- an may carry additional -COOH or SO3H functional groups, C6-C20 cycloalkylene or a mixture of such groups, or a mixture of groups of formula IV and A groups; n is a number from 5 to 500. Compounds of the formulae (I) to (III) are suitable for use as film-forming agents and conditioners in cosmetic preparations for the hair, to stabilize aqueous solutions of hydrogen peroxide, as an iodine-complexing agent, as a binder in tablets and as a component of film coatings for pharmaceutical preparations, to stabilize enzyme and bleach additives in washing and cleaning agents, as an auxiliary in the manufacture and finishing of textiles, as a solubilizer and protective colloid in the manufacture and stabilization of polymer dispersions and as a raw material for adhesives.
