Abstract
Provided are a method for producing a polyamide including an amide-based molecular weight controller and a polyamide produced thereby, wherein the amide-based molecular weight controller may easily control the molecular weight of the polyamide to have a narrow molecular weight distribution so as to prevent an increase in the molecular weight due to a basic intermediate produced in anionic polymerization and a side reaction generated under a high-temperature polymerization condition.
