Description

Verfahren zur Herstellung von Polyamidlösungen Nach dem Verfahren des Patents goS 067 verwendet man zur Herstellung von Polyamidlösungen als Lösungsmittel Trichloräthanol, gegebenenfalls in Mischung mit Alkoholen und/oder halogenierten Kohlenwasserstoffen, oder Chloralhydrat in Mischung mit Trichloräthanol und/oder Alkoholen und/oder halogenierten Kohlenwasserstoffen.Process for the production of polyamide solutions According to the procedure of GoS 067 patents are used as a solvent for the production of polyamide solutions Trichloroethanol, optionally mixed with alcohols and / or halogenated Hydrocarbons, or chloral hydrate mixed with trichloroethanol and / or Alcohols and / or halogenated hydrocarbons.

Es wurde nun gefunden, daß man Polyamidlösungen auch herstellen kann, indem man als Lösungsmittel Trichloräthanol anstatt in Verdünnung mit Alkoholen undXoder mit halogenierten Kohlenwasserstoffen in Mischung mit Wasser und gegebenenfalls zusätzlich Chloralhydrat oder aber letzteres anstatt in Verdünnung mit Trichloräthanol und/oder Alkoholen und/oder halogenierten Kohlenwasserstoffen ebenfalls in Mischung mit Wasser verwendet. It has now been found that polyamide solutions can also be produced by using trichloroethanol as a solvent instead of diluting it with alcohols andXor with halogenated hydrocarbons mixed with water and optionally additionally chloral hydrate or the latter instead of diluted with trichloroethanol and / or alcohols and / or halogenated hydrocarbons, likewise in a mixture used with water.

Wenn man Trichloräthanol und Chloralhydrat bzw. aus beiden Stoffen bestehende Gemische mit Wasser verschneidet, so tritt nicht eine Beeinträchtigung der Lösewirkung auf, sondern es konnte im Gegenteil festgestellt werden, daß durch den Zusatz von Wasser die Polynmidlösungen sich sogar leichter herstellen lassen. Das Wasser kann in einer Menge bis zu 40 ovo zugesetzt werden. If you have trichloroethanol and chloral hydrate or from both substances If existing mixtures are mixed with water, there is no impairment the dissolving effect on, but on the contrary it could be established that by the addition the polynmide solutions are even easier to produce with water permit. The water can be added in an amount up to 40 ovo.

Beispiele I. Es werden 60 Teile Chloralhydrat mit 20 Teilen Wasser und 20 Teilen Polyhexamethylenadipinamid I Stunde bis zur klaren Lösung verrührt. Examples I. 60 parts of chloral hydrate with 20 parts of water and 20 parts of polyhexamethylene adipamide 1 hour stirred until a clear solution.

2. 50 Teile Chloralhydrat werden mit 40 Teilen Wasser und 10 Teilen Polyhexamethylenadipinamid vermischt und bis zur klaren Lösung gerührt. 2. 50 parts of chloral hydrate are mixed with 40 parts of water and 10 parts Polyhexamethylene adipamide mixed and stirred until a clear solution.

3. 40 Teile Chloralhydrat, 20 Teile Wasser, 20 Teile Trichloräthanol und 20 Teile Polyhexamethylenadipinamid werden etwa I Stunde miteinander verrührt, bis eine klare Lösung entstanden ist, die auf Filme verarbeitet werden kann. 3. 40 parts of chloral hydrate, 20 parts of water, 20 parts of trichloroethanol and 20 parts of polyhexamethylene adipamide are stirred together for about 1 hour, until a clear solution is obtained that can be processed onto films.
