| abstract | (57) [Summary] [Structure] From any unit selected from hexamethylene terephthalamide unit, (1) hexamethylene isophthalamide unit, (2) hexamethylene adipamide unit and (3) caproamide unit. In producing a crystalline copolyamide, the dicarboxylic acid component or diamine component is charged in an excess of 0.3 to 10 mol% with respect to the total number of moles of the constituent monomer and the salt dicarboxylic acid component unit and the diamine component unit. 25% of 1% sulfuric acid solution A process for producing a polyamide resin, which comprises producing a primary condensate having a relative viscosity (ηr) at 1.6 ° C. of more than 1.6 and not more than 2.5, and then increasing the degree of polymerization of the primary condensate. [Effect] By using the production method of the present invention, a crystalline copolyamide resin having good heat resistance can be easily produced. |
