Abstract: The present invention relates to a process for the preparation of an aliphatic or partially aromatic polyamide, in which an aqueous composition of the monomers is subjected to an oligomerization at elevated temperature and increased pressure, the reaction mixture is optionally subjected to a first decompression to reduce the water content, the (optionally decompressed) reaction mixture is heated within a short time to a temperature above the melting temperature of the polyamides and the heated reaction mixture is subjected to a (further) decompression to reduce the water content and to an after-polymerization.

Abstract: La presente invención se refiere a un método para la producción de un poliaril éter por reacción de los componentes (a1) y (a2) en presencia de un compuesto de carbonato (C) para obtener un polímero que contiene sal (sP) que contiene el poliaril éter y una sal (S). Posteriormente a la reacción, la sal (S) se extrae del polímero que contiene la sal (sP) para obtener un polímero desalinizado (eP) que contiene el poliaril éter.
