Es wurde gefunden, daß Alkylolamine, die am Stickstoffatom mindestens 1 Wasserstoffatom enthalten und mindestens eine Hydroxylgruppe besitzen, welche durch eine aliphatische, mindestens 10 Kohlenstoffatome enthaltende Carbonsäure verestert ist, in Form ihrer Salze mit starken Säuren — z. B. mit Salzsäure, Schwefelsäure, Salpetersäure, Phosphorsäure oder Methylschwefelsäure — hervorragend zur Verhinderung der elektrostatischen Aufladung von synthetischen Hochpolymeren zu verwenden sind.It has been found that alkylolamines which contain at least 1 hydrogen atom on the nitrogen atom and have at least one hydroxyl group substituted by an aliphatic, at least 10 carbon atoms containing carboxylic acid is esterified, in the form of its salts with strong acids - z. B. with Hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid or methylsulfuric acid - excellent for Prevention of electrostatic charging of synthetic high polymers are to be used.

Als Alkylolamine, die den zu verwendenden Salzen zugrunde liegen, kommen z. B. Äthanolamin, N-Methyl-, N-Äthyl-, N-Propyl- oder N-Cyclohexyläthanolamin und die entsprechenden Propanolamine in Betracht. Als Carbonsäuren, die zur Veresterung gedient haben, kommen Laurinsäure, Palmitinsäure und Ölsäure, ferner die entsprechenden synthetisch gewonnenen Carbonsäuren mit gerader oder verzweigter Kohlenstoffkette sowie solche Carbonsäuren, deren Kohlenstoffkette durch Heteroatome unterbrochen ist, wie Lauryloxyessigsäure, in Frage. Die Anwendung der genannten Mittel auf die synthetischen Hochpolymeren, z. B. auf Fasern, Fäden, Gewebe oder Pulver aus Polyamiden, Polyestern, Polyacrylnitril oder Polyvinylchlorid, erfolgt in an sich bekannter Weise, z. B. durch Besprühen oder Tränken der zu behandelnden Materialien mit Lösungen bzw. Dispersionen der Mittel in organischen Lösungsmitteln bzw. in Wasser.As alkylolamines on which the salts to be used are based, z. B. ethanolamine, N-methyl, N-ethyl-, N-propyl- or N-cyclohexylethanolamine and the corresponding propanolamines into consideration. As carboxylic acids that are used for esterification lauric acid, palmitic acid and oleic acid, as well as the corresponding synthetically obtained ones Carboxylic acids with a straight or branched carbon chain and those carboxylic acids, whose carbon chain is interrupted by heteroatoms, such as lauryloxyacetic acid in question. The application of the agents mentioned to the synthetic high polymers, e.g. B. on fibers, threads, Fabric or powder made of polyamides, polyesters, polyacrylonitrile or polyvinyl chloride is made in on known manner, for. B. by spraying or soaking the materials to be treated with Solutions or dispersions of the agents in organic solvents or in water.

Es ist bereits bekannt, zur Verhinderung der elektrostatischen Aufladung synthetischer Hochpolymerer Alkylolaminabkömmlinge zu verwenden, und zwar solche, die durch partielle Veresterung von Trialkylolaminen mit höheren aliphatischen Carbonsäuren gewonnen sind, oder solche, die durch Salzbildung aus Trialkylolaminen und mit höheren aliphatischen Alkoholen partiell veresterter Schwefelsäure erhalten sind. Vor diesen Mitteln zeichnen sich die Salze gemäß Anspruch durch eine überraschend stärkere antielektrostatische Wirkung aus. Bemerkenswert ist ferner, daß durch die Verwendung der Salze gemäß Anspruch praktisch alle synthetischen Materialien hervorragend antistatisch gemacht werden, ohne daß sie dabei ungünstig beeinflußt werden.It is already known to prevent electrostatic charging of synthetic high polymers To use alkylolamine derivatives, namely those obtained by partial esterification of Trialkylolamines with higher aliphatic carboxylic acids are obtained, or those obtained by salt formation from trialkylolamines and sulfuric acid partially esterified with higher aliphatic alcohols are preserved. The salts stand out from these agents by a surprising one stronger anti-static effect. It is also noteworthy that through the use of the salts according to claim practically all synthetic materials can be made excellent antistatic without that they are adversely affected thereby.
