     KunststoffkörperÜberzüge   hergestellt werden   können,   Ferner zeigen auch bereits die   obenzitiertenpolyamidcarbon-     säure-Zwischenstufen   eine geringe Löslichkeit in den üblichen Lösungsmitteln; ihre Verarbeitung ist deshalb vielfach auf die Verwendung   spezieller Lösungsmittel   wie   Dimethylformamid, Dimethylacet-   amid oder N-Methylpyrrolidon angewiesen.

  Process for the production of imide groups and
Plastics containing ester groups
 EMI1.1
    Types of acid groups with the secondary amino groups of the amide function and with the hydroxyl groups that are still present then take place during the condensation of the plastics. These known methods have disadvantages.



   The resulting plastics containing polyimide groups are generally insoluble and
 EMI1.2
 



     Plastic body coatings can also be produced. In addition, the polyamidocarboxylic acid intermediates cited above also show low solubility in the usual solvents; Their processing is therefore often dependent on the use of special solvents such as dimethylformamide, dimethylacetamide or N-methylpyrrolidone.
