METHOD OF MANUFACTURING A POLYAMIDE WITH AN ANIONIC POLYMERIZATION

摘要

The present invention relates to a method for producing polyamide, which includes a step of polymerizing a first component and a second component. The first component includes lactam having 4-12 carbon atoms and an aliphatic isocyanate compound having at least two isocyanate groups as an activator, whereas the second component includes lactam having 4-12 carbon atoms and an anionic catalyst.
