<p>A fluorine-containing vinyl ether compound, represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRfO(C 3 F 6 O) a (C n F 2n )(C m H 2m ) b CH 2 OCH=CH 2
(where Rf is a polyfluoroalkyl group having 1 or more carbon atoms, a is 0, or an integer of 1-30, b is an integer of 1-10, and n and m each are 1 or 2), is produced by subjecting a fluorine-containing alcohol, represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRfO(C 3 F 6 O) a (C n F 2n )(C m H 2m ) b CH 2 OH
and an alkyl vinyl ether, represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒXCH 2 CH 2 OCH=CH 2
(where X is a halogen atom, a hydrogen atom, or an alkyl group having 1-10 carbon atoms) to XCH 2 CH 2 OH-elimination reaction in the presence of a palladium-based catalyst, and has a fluorine-containing polyether group originating from the hexafluoropropene oxide polymer, and thus is not so rigid as the perfluoroalkyl alkyl group of perfluoroalkyl vinyl ether, rather more flexible, and furthermore has distinguished thermal and chemical stabilities, and also good optical properties and surface-active characteristics together.</p> |
