in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms (C08G77/42 takes precedence)

Introduced: July 1974

Title

Titles differ between systems:

IPC: in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms

CPC: in which at least two but not all the silicon atoms are connected by linkages other than oxygen atoms (C08G77/42 takes precedence)

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

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)

Of 5 combined children, 4 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1974.
