| titleOfInvention | Method for producing polyamide |
| abstract | Provided is a method for producing a polyamide that has an exceptional appearance after heating. The method for producing a polyamide includes: a step for heating a composition that contains a diamine represented by formula (1), a dicarboxylic acid, and a solvent; and a step for removing the solvent during and after the composition heating step, or only after the heating step. The method also includes adding a basic compound and/or a base generator to the composition during the composition heating step and/or before the heating step. In formula (1), X is a hetero atom, and n is an integer of 0-5. The portion of the ring including X represents a cyclic structure including X. |
