Patent

CA 2030800

-61- ABSTRACT The present invention is directed to a compound and a process for preparing a compound having at least one perfluorocyclobutane ring and at least two functional groups suitable for forming condensation polymers. Preferably the compound has a structure represented by the following Formula II: Formula II Image wherein R and R' independently represent optionally inertly substituted groups; X and X' represent any molecular structures which link R and R' with the perfluorocyclobutane ring; n and n' are integers of at least 1, respectively; and G and G' independently represent any reactive functional group or any group convertible into a reactive functional group. -62- The compound is preferably prepared by a process of thermally dimerizing a trifluorovinyl compound to form a compound of the following Formula I: Formula I Gn-R-X-CF=CF2 wherein G represents G or G' of Formula II; X represents X or X' of Formula II; and n represents n or n' of Formula II, to form a compound having a perfluorocyclo- butane group.
