Abstract
NEW MATERIAL:Perfluoro-4-pentenoyl fluoride shown in formula CF2= CF(CF2)2 COF.
USE: A comonomer supplying a crosslinking part of F-containing polymers, a monomer for the synthesis of functional F-containing polymers, a synthetic material of vinyl ethers (synthetic monomer of F-containing polymers with a vinyl side-chain), etc.
PROCESS: An unsym-dioxyfluoride of the formula obtained by the reaction of perfluoro-γ-butyrolactone and hexafluoropropylene epoxide is subjected to the thermal decomposition at 340°C to give perfluoro-4-pentenoyl fluoride, wherein the unsym- dioxyfluoride is introduced into the reactor in the form of vapor diluted with an inert gas, and then thermally decomposed in the presence of a small amount of water
