Polyamidation process |
| abstract |
In a process for the preparation of fiber-forming polyamides in the presence of a phenylphosphinate where copper from a cupric salt employed in the process tends to precipitate from the system, such copper loss is substantially reduced by using a mol ratio of KBr:KI of greater than 0.33 with 0.7 to 9 mols KI at a total potassium halide concentration of from 7.5 to 26 mols per million grams of polymer. |
