PURPOSE: A manufacturing method of a polyamide resin is provided to manufacture a polyamide resin with improved heat resistance by improving the increase of a heat decomposition temperature while water absorption is maintained. CONSTITUTION: A manufacturing method of a polyamide resin comprises a step of manufacturing a reactant by the reaction of a monomer including 2-pyrrolidone and a quaternary ammonium halide; and a step of polymerizing the reactant while carbon dioxide is supplied to the reactant according to the reaction step. In the chemical formula 1, each of R1-R3 is a C1-C5 alkyl group; and X is an alkali metal atom. |
