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 > Germanium, tin, lead, arsenic, antimony, bismuth, titanium, zirconium, hafnium, vanadium, niobium, tantalum, or compounds thereof

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 > Germanium, tin, lead, arsenic, antimony, bismuth, titanium, zirconium, hafnium, vanadium, niobium, tantalum, or compounds thereof

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1990.
