Polyfluorohydrocarbon group-containing monomers, their polymers and applications of the polymers

Abstract

A polyfluorohydrocarbon group-containing acrylate of the formula (1): R.sub.f --(CH.sub.2).sub.n --Q--(CH.sub.2).sub.h --.phi.--[X--.phi.--].sub.y --(CH.sub.2).sub.m OC(O)CR.dbd.CH.sub.2(1) wherein R.sub.f is a polyfluorohydrocarbon group having from 2 to 22 carbon atoms to which fluorine atoms are bonded, wherein some of such carbon atoms may be substituted by ether-type oxygen atoms, .phi. is a p-phenylene group which may be substituted by one or more halogen atoms selected from fluorine and chlorine, provided that when a plurality of .phi. are present in one molecule, such a plurality of .phi. may be the same or different from one another, R is a hydrogen atom, a methyl group, a fluorine atom, a chlorine atom or a bromine atom, Q is an oxygen atom or a sulfur atom, X is a single bond, --CH.dbd.CH--, --N.dbd.CH--, --CH.dbd.N-- or --C(O)--, n is an integer of from 1 to 22, h is an integer of from 0 to 22, m is an integer of from 1 to 11, and y is an integer of from 0 to 5.
