C08G 77/50

by carbon linkages

Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Macromolecular compounds obtained by reactions forming in the main chain of the macromolecule a linkage containing silicon, with or without sulfur, nitrogen, oxygen, or carbon > in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms > by carbon linkages

CPC:

Macromolecular compounds obtained by reactions forming a linkage containing silicon with or without sulfur, nitrogen, oxygen or carbon in the main chain of the macromolecule > in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms (C08G77/42 takes precedence) > by carbon linkages

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

IPC defines codes here since 1974.
