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 > Polyesters containing atoms other than carbon, hydrogen, and oxygen > containing silicon
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) > Polyesters containing atoms other than carbon, hydrogen and oxygen (C08G63/64 takes precedence) > containing silicon
Of 2 combined children, 0 exist in both systems.
2 codes are CPC-only extensions.
