DIFF Subgroup
C08G 75/20 Polysulfones
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 sulfur, with or without nitrogen, oxygen, or carbon > Polysulfones
CPC:
Macromolecular compounds obtained by reactions forming a linkage containing sulfur with or without nitrogen, oxygen, or carbon in the main chain of the macromolecule > Polysulfones
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1974.
