Continuous solid-state polymerization process and reactor column for use therein |
| abstract |
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, 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. |
