Novel polymers containing alternating perfluorocyclobutane and aromatic ether subunits are prepared from aryl poly(trifluorovinyl ether) monomers via the thermal [2{pi} + 2{pi}] dimerization of the trifluorovinyl ether functionality. The bifunctional monomer 4,4`-bis(trifluorovinyloxy)biphenyl and the trifunctional monomer 1,1,1-tris-(4-trifluorovinyloxyphenyl)ethane are prepared and polymerized to provide thermoplastic and thermoset polymers, respectively. Characterization of the mechanical and dielectric properties of these new polymers is presented.
