    摘要： The present invention describes a process for preparing a poly(aryl ether ketone) by reacting a nucleophile with 4,4′-difluorobenzophenone (4,4′-DFBP) that is improved through the use of 4,4′-DFBP that meets one or more particular purity conditions. Also described are improved poly(aryl ether ketone) produced using the invention 4,4′-DFBP. Amounts of 2,4′-difluorobenzophenone (2,4′-DFBP), 4-monofluorobenzophenone (4-FBP), chlorine, and monochloromonofluorobenzophenone in 4,4′-DFBP are discussed.
