Abstract
The applicability of Fourier IR spectroscopy to determination of the content of sulfonyl fluoride groups in the copolymer of tetrafluoroethylene with perfluoro(3,6-dioxa-4-methyl-7-octene)sulfonyl fluoride (F-4SF copolymer) was examined. A procedure was suggested for determination of sulfonyl fluoride groups, based on a correlation between the analytical signals in the IR absorption spectrum of F-4SF and the sulfur content in F-4SF samples.
