only aromatic carbon atoms, e.g. polyphenylenes

Full Title

Macromolecular compounds obtained by reactions forming a carbon-to-carbon link in the main chain of the macromolecule (C08G2/00 - C08G16/00 take precedence) > Macromolecular compounds containing only carbon atoms in the main chain of the macromolecule, e.g. polyxylylenes > only aromatic carbon atoms, e.g. polyphenylenes
