Abstract
The present invention provides a method for producing a polyamide with controlled activator addition, and a polyamide produced thereby, the method allowing a polymerization conversion rate and a polydispersity index (PDI) to be enhanced by controlling the addition of an activator so as to prevent a gelation phenomenon that occurs during anionic polymerization.
