Preparation processes

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

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

Of 5 combined children, 4 exist in both systems.

1 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
