Beschreibung
Zusammenfassung:	The invention relates to a continuous solid-state polymerization process for preparing a polyamide derived from diamine and dicarboxylic acid, wherein the salt is polymerized in a reactor column comprising successive multifunctional zones comprising heating sections and gas-outlet sections, and a residence zone comprising at least one gas-inlet section, wherein the heating sections comprise static heat exchangers. The invention also relates to the reactor column and use thereof in a continuous solid-state polymerization process.
