    摘要： A process for the production of water-dilutable binders based on air-drying short-oil alkyd resins acidified by semiester formation with dicarboxylic acid anhydrides which alkyd resins have acid numbers of from 30 to 70 and hydroxyl numbers of from 40 to 120 and a content of natural unsaturated fatty acids in an amount of from 15 to 50 % by weight and of a co-condensed natural-resin-modified phenol resol resin in an amount of from 2 to 10 % by weight, characterized in that 1. the molar composition of the alkyd resin before semiester formation corresponds to a polyalcohol/polycarboxylic acid (anhydride)/monocarboxylic acid ratio of 1 : (0.5-1) : (0.3-1), and 2. polyalcohols, polycarboxylic acids resp. their anhydrides, monocarboxylic acids and phenolic resins are co-condensed in a single process stage, followed only by semiester formation with dicarboxylic acid anhydrides.

    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.
