摘要

PEEK (poly(etheretherketone)) is a high temperature thermoplastic which can be compression moulded and extracted [1]and has many uses, with applications in the automotive, oil and aerospace industries [2]. PEEK is usually prepared via a high temperature condensation of 4,4′-difluorobenzophenone (BDF) with hydroquinone [3]. While hydroquinone is readily available, BDF is expensive and contributes greatly to the overall cost of PEEK. Numerous methods exist in the literature ...
