Description

Verfahren zur Herstellung von alkali- und säurebeständigen, stickstoffhaltigen Kunststoffen Im Patent 689 15 i ist ein Verfahren zur Herstellung von aIkali- und säurebeständigen, stickstoffhaltigen Kunststoffen unter Schutz gestellt, bei dem aromatische Isocyanate oder Isothiocyanate und Äthylenimin oder seine Homologen oder Polymere dieser Stoffe gemeinsam z. B. durch Einwirkung von Wärme oder Chemikalien, wie Säure oder Alkali, polymerisiert werden.Process for the production of alkali and acid-resistant, nitrogen-containing plastics In the patent 689 1 5 i, a process for the production of alkali and acid-resistant, nitrogen-containing plastics is protected, in which aromatic isocyanates or isothiocyanates and ethyleneimine or its homologues or polymers of these substances together z. B. polymerized by exposure to heat or chemicals such as acid or alkali.

In Weiterentwicklung dieses Verfahrens hat sich nun herausgestellt, daß man auch dann zu wertvollen Kunststoffen gelangt, wenn die Umsetzung, wie sie im Hauptpatent beschrieben ist, in Gegenwart von Cyclohexanon durchgeführt wird. Die so erhaltenen Kunststoffe zeigen die gleichen Eigenschaften wie die nach dem Hauptpatent erhaltenen; sie sind in Säuren und Alkalien vollkommen unlöslich und lassen sich ausgezeichnet mit sauren Wollfarbstoffen anfärben.In the further development of this process it has now been found that you can get valuable plastics even if the implementation is like it is described in the main patent, is carried out in the presence of cyclohexanone. The plastics obtained in this way show the same properties as those after Main patent obtained; they are completely insoluble in acids and alkalis and can be dyed with acidic wool dyes.

Beispiel ioo ccm 98prozentiges Äthylenimin werden in ioo ccm Benzol gelöst und mit 230 ccm Cyclohexanon versetzt. Die Temperatur steigt dabei bis 5o° an. Die erhaltenen langen Nadeln gehen beim Erwärmen auf dem Wasserbad in Lösung, und man gibt nun zu dieser Lösung allmählich Zoo ccm frisch destilliertes Phen,-lisocyanat. Dauer der Zugabe 6 Stunden. Nach Beendigung der Reaktion wird das Ganze nochmals 8 Stunden auf dem Dampfbad erhitzt. Das erhaltene braune Harz ist in Säuren und Alkalien vollkommen unlöslich und läßt sich sehr gut mit sauren `Vollfarbstoffen anfärben.Example 100 cc of 98 percent ethyleneimine are dissolved in 100 cc of benzene and 230 cc of cyclohexanone are added. The temperature rises to 50 °. The long needles obtained dissolve when heated on a water bath, and zoo cc of freshly distilled phen-isocyanate are gradually added to this solution. The addition takes 6 hours. After the reaction has ended, the whole is heated again on the steam bath for 8 hours. The brown resin obtained is completely insoluble in acids and alkalis and can be very easily colored with acidic full dyes.
