C08G65/4031 - CPC Classification

Classification description:

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; Other compound (II) containing a ketone group, e.g. X-Ar-C(=O)-Ar-X for polyetherketones (I) or (II) containing nitrogen
