PURPOSE: A polyamide copolymer is provided to derive increase of a thermal decomposition temperature and decrease of melting point while maintaining high moisture absorption, thereby capable of improving spinning processability and heat resistance. CONSTITUTION: A polyamide copolymer comprises a repeating unit represented by chemical formula 1. In chemical formula 1, n is an integer from 5-36, x+y=1, 0<x<1, and 0<y<1. A manufacturing method of the polyamide copolymer comprises a step of preparing a polyamide copolymer by polymerizing C5-36 lactam and 2-pyrroidione as monomers, and uses one or more kinds of initiators selected from compounds in chemical formula 2-5. In chemical formula 2-5, n is an integer from 1-11, l and m is respectively an integer from 0-10. |
