To the question of the synthesis of aromatic copolyether sulfone ketones

Abstract

Synthesis reactions and physico-mechanical, thermal properties of new aromatic copolyethersulfone ketones were studied in relation to the chemical structure of activated dihaloarenes and diols in a simpler, more economical way. It is shown that by controlling the ratio of monomers and the order of their introduction into the copolycondensation reaction, it is possible to obtain aromatic copolyethersulfone ketones with increased temperature and physicomechanical characteristics.
