from phenols (I) and other compounds (II), e.g. OH-Ar-OH + X-Ar-X, where X is halogen atom, i.e. leaving group

Introduced: July 1974

Title

Titles differ between systems:

IPC: from phenols and other compounds

CPC: from phenols (I) and other compounds (II), e.g. OH-Ar-OH + X-Ar-X, where X is halogen atom, i.e. leaving group

Full Title

Full titles differ between systems:

IPC:

Macromolecular compounds obtained by reactions forming an ether link in the main chain of the macromolecule > from hydroxy compounds or their metallic derivatives > derived from phenols > from phenols and other compounds

CPC:

Macromolecular compounds obtained by reactions forming an ether link in the main chain of the macromolecule > from hydroxy compounds or their metallic derivatives > derived from phenols > from phenols (I) and other compounds (II), e.g. OH-Ar-OH + X-Ar-X, where X is halogen atom, i.e. leaving group

CPC subdivides this area 7x more granularly than IPC with 6 additional codes.

6 codes are CPC-only extensions.

IPC defines codes here since 1974.
