METHOD OF PRODUCING POLYESTER KETONES Russian patent published in 2018 - IPC C08G65/40

Abstract RU 2669793 C1

FIELD: technological processes.

SUBSTANCE: invention relates to a process for the preparation of polyether ketones that can be used as superconstructive polymeric materials. Method for producing polyether ketones is that a dihalide derivative and hydroxy compounds are reacted, phenolic red comonomer and potassium carbonate in the presence of a solvent at a reaction temperature of 165.5 °C for 5 hours. As a solvent, dimethylacetamide is used.

EFFECT: invention makes it possible to obtain polyether ketones in a single-step process.
