摘要： Polyetheretherketone (PEEK) may be prepared by polycondensation of a single monomer (4-fluoro-4′-(4-hydroxyphenoxy) benzophenone) in diphenylsulphone (DPS) solvent and in the presence of sodium carbonate and potassium carbonate. The process can be used to produce high quality, relatively light coloured polymers having a lower Tm than those produced using a standard PEEK process.
