Description

Weichmachungsmittel Es wurde gefunden, daß die Dibenzyläther von Glykolen hervorragende Weichmachungsmittel für Polyvinylchlorid und vinylchloridha.ltige Mischpolymerisate sind. Geeignete Dibenzyläther von Glykolen sind vornehmlich solche von Glykolen mit zwei primären Hydroxylgruppen, z. B. Diglykol, i, 3-Propandiol, i, 4-Butandiol, i, 6-Hexandiol, i, io-Decandiol. Auch Dibenzyläther von Glykolen, deren Kette durch Sauerstoff oder Schwefel unterbrochen ist, beispielsweise Diglykol, Triglykol, Thiodiglykol, kommen in Frage. Schließlich kann man auch die Dibenzyläther von Glykolen, die eine oder zwei sekundäre Hydroxylgruppen besitzen, z. B. i, 3-Butyl.englykol, 2-Athylhexandiol-i, 3 und 3, 8-Dioxy-2, 9-dimethyldecan, verwenden. Die erwähnten Äther zeichnen sich neben ihrer chemischen Beständigkeit vor allem dadurch aus, daß die mit ihnen hergestellten Massen eine sehr günstige Kältefestigkeit sowie gute elektrische Eigenschaften besitzen. Äther der erwähnten Art kann man beispielsweise :durch Umsetzen von. Benzylchlorid oder dessen Kern@substitutionsprodukten mit Alkaliglykolaten bei Temperaturen zwischen ioo und 200° erhalten, wobei man zweckmäßig in Gegenwart eines inerten Lösungsmittels arbeitet.Softeners It has been found that the dibenzyl ethers of glycols excellent plasticizers for polyvinyl chloride and vinyl chloride-containing substances Copolymers are. Suitable dibenzyl ethers of glycols are primarily those of glycols with two primary hydroxyl groups, e.g. B. diglycol, i, 3-propanediol, i, 4-butanediol, i, 6-hexanediol, i, io-decanediol. Also dibenzyl ethers of glycols, whose chain is interrupted by oxygen or sulfur, for example diglycol, Triglycol, thiodiglycol, are possible. Finally, you can also use the dibenzyl ether of glycols having one or two secondary hydroxyl groups, e.g. B. i, 3-butyl.englycol, Use 2-Ethylhexanediol-1, 3 and 3, 8-Dioxy-2, 9-dimethyldecane. The mentioned In addition to their chemical resistance, ethers are primarily characterized by that the masses produced with them have a very favorable cold resistance as well have good electrical properties. Ether of the kind mentioned can be used, for example : by converting. Benzyl chloride or its core @ substitution products with alkali glycolates obtained at temperatures between 100 and 200 °, advantageously in the presence an inert solvent works.

Infolge ihrer guten elektrischen Eigenschaften eignen sich die erhaltenen Massen, besonders zur Herstellung von Gleichstromkabeln, da. sie unter dem Einfluß der Spannung keine Zersetzung erleiden.Due to their good electrical properties, those obtained are suitable Masses, especially for the production of direct current cables, there. them under the influence do not undergo decomposition due to the tension.

Beispiel Ein bei ioo bis 12o° vorgelatiniertes Gemisch aus 6o Gewichtsteilen Polyvinylchlorid und 4o Gewichtsteilen i, 6-Hexandioldibenzyläther wird io Minuten lang bei 16o° verwalzt. Man erhält eine farblose, klare und transparente Folie, die eine Festigkeit von 16o kg/cm2 bei einer Dehnung von 390% besitzt. Bei einer fünftägigen Heißluftalterung bei 70° erleidet die Folie nur einen Gewichtsverlust von etwa 2%, ohne daB die mechanischen Eigenschaften verschlechtert werden. Die Folien halten eine Abkühlung bis auf -.45' ohne Zerbrechen aus..Example A mixture of 60 parts by weight pregelatinized at 100 to 120 ° Polyvinyl chloride and 40 parts by weight of i, 6-hexanediol dibenzyl ether is 10 minutes rolled long at 16o °. You get a colorless, clear and transparent one Foil that has a strength of 160 kg / cm2 at an elongation of 390%. at after aging in hot air at 70 ° for five days, the film suffers only a weight loss of about 2%, without the mechanical properties being impaired. the Foils can withstand cooling to -.45 'without breaking.

Eine in analoger Weise mit dem r, 4-Butandioldibenzyläther hergestellte Folie besitzt eine Festigkeit von i8o kg/cm2 bei einer Dehnung von 3700/0. Sie bricht erst beim Abkühlen auf -40°. Unter Verwendung des. Diglykoldibenzylätliers in der oben angeführten Weise hergestellte Folien besitzen eine Festigkeit von 177 kg/cm2 bei .lio °/o Dehnung. Sie brechen erst bei -4o°.A film produced in an analogous manner with r, 4-butanediol dibenzyl ether has a strength of 180 kg / cm2 at an elongation of 3700/0. It only breaks when it cools down to -40 °. Films produced using the diglycol dibenzyl ether in the above-mentioned manner have a strength of 177 kg / cm.sup.2 at 100% elongation. They only break at -4o °.
