METHOD OF SYNTHESIS OF FLUORINE-CONTAINING POLYMERS Russian patent published in 1996 - IPC

Abstract RU 2064938 C1

FIELD: fluoro-containing polymers. SUBSTANCE: 2,2,3,3-tetrafluoropropyl--α--fluoroacrylate is subjected for polymerization in mass in the presence of 15-20 wt.-% of monomer 2,2,3,3,4,4,5,5-octafluoroamylacrylate, 0.02-0.05 mas. p. of p-methoxyphenol monomers mass and 0.24-0.28 mas. p. of n-dodecylmercaptane monomers mass. Isobutyric acid azodinitrile is used as initiating agent (0.06-0.07 mas. p. of monomers mass). Synthesized polymers were used in radiotechnics, instrument making and chemical industries. EFFECT: improved method of synthesis. 9 ex, 1 tbl
