Abstract (en)
[origin: DE10114690A1] The invention relates to a method of producing polyamides in an aqueous reaction mixture that contains a nitrile, selected from 6-aminocapronitrile and adipodinitrile. The inventive method is characterized by using a nitrile through which, in its liquid state, a gas that is inert with respect to the nitrile, was led.
[origin: DE10114690A1] Preparation of a polyamide comprises using a nitrile from 6-aminocapronitrile and adiponitrile in an aqueous reaction mixture and introducing an inert gas. An Independent claim is included for the obtained polyamide.
