Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a polyamide by coordinated anionic ring-opening polymerization and a polyamide produced thereby, wherein metal alkoxide as an initiator and metal hydride as a catalyst are added to enable polymerization having a narrow molecular weight distribution and uniform molecular weight within a short polymerization reaction time at a low temperature, without a separate vacuum process, as compared with an existing polymerization method.
