WebDie Struktur von PEEK enthält zwei Ethergruppen zwischen den beiden Phenylringen und eine Ketogruppe neben jedem Phenylring. PEK hat eine ähnliche chemische Struktur wie PEEK, unterscheidet sich jedoch dadurch, dass es nur eine Ethergruppe zwischen den beiden Phenylringen hat, anstatt wie bei PEEK zwei Ethergruppen. In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph.
