PURPOSE: A manufacturing method of a nylon 4,6 copolymer is provided to manufacture the 4,6 copolymer with excellent mechanical properties and processability by improving molecular weight properties and thermal properties.;CONSTITUTION: A manufacturing method of a nylon 4,6 copolymer comprises a step of copolymerizing 2-pyrroidone as a monomer, and epsilon-caprolactam. The copolymer molar ratio of the 2-pyrolidone and epsilon-caprolactam is 9:1-1:1. An initiator for the copolymerization is selected from carbon dioxide, N-acyllactam, and N-acetylpyrrolidone. A main catalyst thereof is selected from potassium hydroxide, sodium hydroxide, and potassium carbonate. The additional contents of the main catalyst is 1-20 parts by weight based on 100.0 parts by weight of a raw material monomer, and the addition contents of the initiator is 20-80 parts by weight based on 100.0 parts by weight of the main catalyst.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Flow of heat(W/g); (BB) Temperature(°C)
