C08G 63/82 characterised by the catalyst used
Introduced: January 1990
Full Title
Full titles differ between systems:
IPC:
Macromolecular compounds obtained by reactions forming a carboxylic ester link in the main chain of the macromolecule > Preparation processes > characterised by the catalyst used
CPC:
Macromolecular compounds obtained by reactions forming a carboxylic ester link in the main chain of the macromolecule (polyester-amides C08G69/44; polyester-imides C08G73/16) > Preparation processes > characterised by the catalyst used
Of 6 combined children, 4 exist in both systems.
2 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1990.
