Method and device for producing polyamides with optimized flow guidance |
| abstract |
The invention relates to a method for producing polyamides, in which the flow guidance is more effective. The process is based on the polymerization of lactams into a polymer melt containing polyamide, the subsequent granulation of the polymer melt into polyamide pellets using a granulation liquid, and the subsequent extraction of monomeric and oligomeric components from the PA pellets in an extraction column. The invention also relates to a device for carrying out the method. |
