Abstract
Abstract A polyfluoroalkenyl ether of the formula: wherein X is a chlorine atom or a fluorine atom, Y is a group of the formula: in which M is an alkali metal and R is a hydrogen atom or a lower alkyl group, Z is a fluorine atom or a trifluoroalkyl group, n is an integer of 2 to 6 and m is an integer of 0 to 6, which can be homopolymerized or copolymerized with an ethylenically unsaturated comonomer to give a polymer having improved low temperature properties.
