compounds were prepared from versatileintermediate p-Br-C(6)H(4)-O-CF=CF(2) and underwent thermal radical mediated cyclodimerization to new difunctional compounds containing the 1,2-disubstituted perfluorocyclobutyl (PFCB) linkage. The synthetic scope demonstrates the functional group transformation tolerance of the fluorovinyl ether, and the dimers are useful as monomers for traditional step-growth

A polymer has at least one photoactive site and more than one perfluorocyclobutane group. New monomers containing photoactive sites or photoactive precursors and at least one perfluorovinyl group are useful for making such polymers. Processes of making such polymers and the monomers from which they are made are disclosed. The polymers are useful in coatings, photoresists, and the like.
