METHOD OF PRODUCING COPOLYMER OF TETRAFLUOROETHYLENE WITH 2-FLUOROSULPHONYL PERFLUOROETHYLVINYL ETHER - PROTON-CONDUCTING MEMBRANE PRECURSOR - BY EMULSION COPOLYMERISATION |
摘要 |
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 C-Chydrocarbon, 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.6 cl, 1 tbl, 11 ex |
