PROCESS FOR MANUFACTURING POLYAMIDE |
| 摘要 |
In one or a plurality of embodiments, a process for manufacturing polyamide, with a reduced use of an amide-based solvent in synthesis, is provided. In one or a plurality of embodiments, provided is a process for manufacturing polyamide, including steps (a) to (c): (a) dissolving diacid dichloride in a non-amide-based organic solvent; (b) adding diamine to a solution obtained in the step (a) and reacting the diacid dichloride with the diamine so as to generate polyamide; and (c) adding a trapping reagent capable of trapping hydrochloric acid, at any time at least before the step (b), at the same time of starting the step (b), or during the step (b). |
