Abstract: The preparation of a polymer essentially comprising units of the formula I in which R and R are hydrogen or methyl, and R is C1-C18-alkyl, C5-C12-cycloalkyl, C6-C10-aryl or C6-C10-aryl-C1-C4-alkyl, where these radicals, with the exception of the C1-C18-alkyl radicals, may be up to trisubstituted by radicals selected from the group consisting of C1-C4-alkyl, C1-C4-alkoxy and halogen, by reacting a polymer based on C1-C20-alkyl esters of acrylic acid, methacrylic acid or mixtures thereof with ammonia or a primary amine in an extruder, by vigorously mixing the ammonia or the primary amine with a melt of the polymer to be reacted at a maximum temperature of 250 DEG C before carrying out the imidation, and the use of the polymers prepared by this process for the production of thermoplastic mouldings, films or fibres, and mouldings, films or fibres made from these polymers.
