METHOD OF PRODUCING COPOLYMER OF TETRAFLUOROETHYLENE WITH 2-FLUOROSULPHONYL PERFLUOROETHYLVINYL ETHER - PROTON-CONDUCTING MEMBRANE PRECURSOR - BY EMULSION COPOLYMERISATION Russian patent published in 2015 - IPC C08F2/24 C08F214/26 C08F214/18

Abstract RU 2545182 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing proton-conducting membrane precursors - perfluorinated copolymers with shortened side chains containing sulphonyl fluoride groups. The method includes emulsion copolymerisation of tetrafluoroethylene and 2-fluorosulphonyl perfluoroethylvinyl ether in an aqueous microemulsion of 2-fluorosulphonyl perfluoroethylvinyl ether using a modifying additive - perfluorinated C₆-C₁₀ hydrocarbon, used for regulating optimum composition and molecular characteristics of the obtained copolymers.

EFFECT: obtaining a membrane copolymer with a constant composition with optimum electrochemical properties.
