Abstract
A cis-trans fluoropolyol acrylate prepared by reacting acrylic acid anhyde with a fluoropolyol having the structural formula: ##STR1## where R is selected from the group consisting of --C(CF.sub.3).sub.2 C.sub.6 H.sub.4 C(CF.sub.3).sub.2 -- and --C(CF.sub.3).sub.2 CH.sub.2 CH.dbd.CH(CF.sub.3).sub.2 C--, R' is selected from the group consisting of --H and --CF.sub.2).sub.x F, x is 1 to 8 and n is any integer from 1 to 15, and the crosslinked thermosetting polymer prepared therefrom. The fluoropolyacrylate is useful in fabricating castings, coatings or adhesives.
