Method for preparing a polymer alloy which is stable and homogeneous up to high temperatures, from component (a) one or more polymers of high molecular weight, having anhydride groups and component (b) one or more polymers of high molecular weight, having groups which have the ability to interact with hydrogen atoms to form hydrogen bonds, wherein first a solution of component (a) is prepared in an organic solvent, to which solution then component (b) is added, whereas component (a) in dissolved state is protolyzed in whole or in part, prior to or after the addition of component (b) under the action of protolyzing agents, whereupon the solvent is removed; together with the formed products obtained from such a polymer alloy, such as granules, fibres, foils, foam, etc.
