Es ist bekannt, elastische Polyurethane in der Art herzustellen, daß man Polyester mit endständigen, freien Hydroxylgruppen mit einem Überschuß an Diisocyanaten reagieren läßt und anschließend die entstehenden Isocyanat-Polyester mit Glykolen unter gleichzeitiger Formgebung reagieren läßt. Dieses Verfahren ist in der deutschen Patentschrift 831 772 ausführlich beschrieben.It is known to produce elastic polyurethanes in such a way that one polyester with terminal, allows free hydroxyl groups to react with an excess of diisocyanates and then the resulting isocyanate polyester can react with glycols with simultaneous shaping. This The method is described in detail in German patent specification 831 772.
Weiterhin ist es nach der deutschen Patentschrift 1106 958 möglich, thermoplastisch verarbeitbare Polyurethane dadurch herzustellen, daß ein OH-Gruppen aufweisender Polyester mit einem Molekulargewicht von 250 bis 2500, gebildet aus einem verzweigtkettigen aliphatischen Diol mit 5 bis 10 C-Atomen und folgender Anordnung von '5 5 C-Atomen und einer der beiden OH-GruppenFurthermore, according to the German patent specification 1106 958, it is possible to process them thermoplastically To produce polyurethanes that a polyester containing OH groups and having a molecular weight from 250 to 2500 formed from a branched chain aliphatic diol with 5 to 10 carbon atoms and the following arrangement of '5 5 carbon atoms and one of the two OH groups

und einer Phthalsäure, mit einem aliphatischen Glykol und mit einem aromatischen Diisocyanat in solchen Mengen umgesetzt wird, daß die molare Menge des aromatischen Diisocyanates der Summe der molaren Menge von dem Polyester und aliphatischen Glykol entspricht und auf jedes Mol Polyester 1,1 bis 4 Mol aromatisches Diisocyanat und 0,1 bis 3 Mol Glykol treffen.and a phthalic acid, with an aliphatic glycol and with an aromatic diisocyanate in such Quantities is implemented that the molar amount of the aromatic diisocyanate is the sum of the molar Amount of the polyester and aliphatic glycol corresponds to and for each mole of polyester 1.1 to 4 moles meet aromatic diisocyanate and 0.1 to 3 moles of glycol.
Es wurde nunmehr die interessante Beobachtung gemacht, daß man thermoplastisch verarbeitbare Polyurethane auch in der Art herstellen kann, daß man rein lineare Polyester verwendet, die nicht an die Molekülkonfiguration gemäß der deutschen Patentschrift 1 106 958 gebunden sind. Auch lassen sich Polyäther mit endständig freien OH-Gruppen — soweit sie rein linearen Charakter besitzen — verwenden. The interesting observation has now been made that one can process thermoplastics Polyurethanes can also be produced in such a way that purely linear polyesters are used, which do not adhere to the molecular configuration according to German patent 1 106 958 are bound. Let too polyethers with terminal free OH groups - as far as they have a purely linear character - use.
Im Unterschied zu dem in der deutschen Patentschrift 1 106 958 beschriebenen Verfahren werden

wobei die Menge des eingesetzten Diisocyanats so zu bemessen ist, daß über die zum Absättigen

ein Überschuß an freiem. Isocyanat erhalten bleibt. Vorzugsweise soll als Glykol 1,4-Butandiol oder 1,4-Butendiol zur Anwendung gelangen. Der Polyester soll vorzugsweise aus Adipinsäure und Äthylenglykol bzw. aus Adipinsäure-Butylenglykol hergestellt werden. Es können auch Polyester mit anderen aliphatischen Säuren oder anderen aliphatischen Glykolen sowie Polyester aus Gemischen von aliphatischen Säuren und Glykolen zur Anwendung gelangen. an excess of free. Isocyanate is retained. The preferred glycol is 1,4-butanediol or 1,4-butenediol are used. The polyester should preferably be made from adipic acid and ethylene glycol or from adipic acid-butylene glycol. It can also be polyester with others aliphatic acids or other aliphatic glycols and polyesters from mixtures of aliphatic Acids and glycols are used.
Der geringe Überschuß von Diisocyanaten ist für die Qualität des Endproduktes von ausschlaggebender Bedeutung, da bei der Verarbeitung bei erhöhter Temperatur auf Maschinen zur thermoplastischen Verarbeitung immer eine gewisse Luftfeuchtigkeit vorhanden ist, die mit den freien Isocyanatgruppen noch eine gewisse nachträgliche Vernetzung ergibt. Der geringe Gehalt an freien Isocyanatgruppen wirkt sich — wie sich in praktischen Versuchen gezeigt hat — nicht störend für die Lagerstabilität des Produktes aus. Es konnten beispielsweise noch nach etwa 4 bis 5 Monaten Lagerung bei Raumtemperatur ohne Beeinträchtigung der Verarbeitungseigenschaften Fertigprodukte mit gleichem physikalischem Niveau — wie später angegeben — erreicht werden.The small excess of diisocyanates is crucial for the quality of the end product Significance, because when processing at elevated temperature on machines for thermoplastic Processing there is always a certain humidity that is present with the free isocyanate groups there is still a certain amount of subsequent networking. The low content of free isocyanate groups has - as has been shown in practical tests - does not interfere with the storage stability of the product. For example, it was still possible after about 4 to 5 months of storage Room temperature without impairing the processing properties Finished products with the same physical level - as stated later - can be achieved.
Der Vorteil des erfindungsgemäßen Verfahrens besteht neben einer sehr wirtschaftlichen Fertigungsmöglichkeit darin, daß man die erhaltenen Produkte auf allen Maschinen für thermoplastische Massen hervorragend verarbeiten kann. Weiterhin ist das Qualitätsniveau der Produkte in bezug auf Zerreißfestigkeit und Strukturfestigkeit infolge des weit regelmäßigeren Aufbaues besser als das der bekannten Produkte. Die erfindungsgemäß " hergestelltenThe advantage of the process according to the invention is, in addition to a very economical production possibility, that the products obtained can be used can process excellently on all machines for thermoplastic masses. Furthermore, this is Quality level of the products in terms of tensile strength and structural strength as a result of the far more regular structure than that of the known products.
