Abstract:
The present invention is a method for producing a polyamide resin, wherein a nylon salt obtained from a dicarboxylic acid and a diamine having a boiling point exceeding 100° C. is heated to be polymerized under normal pressure while water vapor is being allowed to be present in the polymerization reaction system.
