Abstract
Fluorine containing oxyvinyl compounds characterized by having one or more oxyvinyl groups separated from fluorine containing groups by at least one alkylene group having 2-8 carbon atoms and by at least one oxygen atom in addition to the oxygen on the oxyvinyl. In general the compounds of the invention have the generic formula: EQU Rz(L).sub.a (Ry).sub.b OROCH.dbd.CH.sub.2. Where L is .dbd.CHCOOROCH.dbd.CH.sub.2 ; a is number of 0 to about 1; R.sub.y is --CO--; b is a number of 0 to about 1; R is cycloalkane or (CH.sub.2).sub.x --, where x is a number of about 2 through about 10; R.sub.z is R.sub.f C.sub.n H.sub.m where R.sub.f is a fluorinated alkylene moiety of about 1 to about 12 carbon atoms which may be linear or branch chained and may contain a further --OROCH.dbd.CH.sub.2 group; n is an integer of about 1 through about 6; and m is an integer of n to 2n. The compounds are suitable for use in optical devices such as fibers and waveguides, are readily radiation curable and curable by other means, and can be formulated to be of low viscosity when applied. The compounds are also suited for coatings, inks and adhesive and other applications. The invention includes methods for pre…
