Method for producing highly viscous polyamides

摘要: The invention relates to a method for synthesizing polyamide, in which an aqueous solution is sprayed onto the polyamide before and/or during solid-state post-condensation process. comprises at least first compound, selected from group comprising phosphoric acid, fully neutralized salts of partially and mixtures thereof, second anhydride, lactone, ammonia, amine, with stipulation that compound not acid anhydride. spraying occurs temperature lies below boiling point water. A can be produced by means according used particular produce films, monofilaments, fibers, threads, or textile sheet materials.
