CPC:

Macromolecular compounds obtained by reactions forming a carboxylic amide link in the main chain of the macromolecule (products obtained from isocyanates or isothiocyanates C08G18/00; polyamide-imides C08G73/14) > Polyamides derived from amino-carboxylic acids or from polyamines and polycarboxylic acids > derived from amino-carboxylic acids > Lactams
