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).

摘要:In one or a plurality of embodiments, a process for manufacturing polyamide without using PrO (propylene oxide) in synthesis is provided. In one or a plurality of embodiments, provided is a process for manufacturing polyamide, including steps (a) to (c): (a) reacting diacid dichloride monomer with at least two kinds of diamine monomers in a solvent so as to generate polyamide; and (b) removing hydrochloric acid physically out of a reaction system, the hydrochloric acid being generated during the reaction in the step (a); or (c) adding a trapping reagent capable of trapping hydrochloric acid, at any time at least before the step (a), at the same time of starting the step (a), or during the step (a), wherein at least one of the diamine monomers is a diamine monomer containing a carboxyl group, and the trapping reagent does not include propylene oxide.
