    摘要： This invention relates to decomposable polyamide masses for packaging materials containing 5 to 25% by weight of an addition of linear, oligomeric aliphatic polyesters or polycarbonates with molecular weights from 800 to 4000. These additives preferably consist of polyesters of aliphatic diols and dicarboxylic acids having up to 10 carbon atoms or aliphatic carbonates having up to 10 carbon atoms.The use of such mixtures for easily degradable, decomposable polyamide packages is also claimed, in particular in the form of films or thin walled injection moulded parts for (food) packaging.

    摘要： The new aromatic ether imides corresponding to the following formula ##STR1## may be used for the production of plastics which in turn may be worked up into moulded articles, films, sheet products and filaments. The plastics produced from the new aromatic ether imides are distinguished by their exceptional dimensional stability under heat.
