Abstract
Polyether ether ketones based on 4,4'-difluorobenzophenone and hydroquinone in sulfolane medium in the presence of anhydrous potassium carbonate were synthesized by the method of high-temperature polycondensation. The rheological, thermal, electrical and physical-mechanical properties are investigated. It is shown that, at processing temperatures, the molecular weight of polyether ether ketones synthesized in sulfolane increases, apparently due to the branching processes of the polymer chain.
