How to Make PEEK?

PEEK can be made by different synthetic methods, but a standard process is a step-growth polymerization generated by the dialkylation of the bisphenolate salts. In this process, 4,4'-difluorobenzophenone reacts with the disodium salt of hydroquinone, and the reaction proceeds in a polar aprotic solvent at a temperature of about 300°C to complete the nucleophilic substitution reaction. The result is to form a robust material with exceptional properties.
