摘要：
The present invention is a process for preparing a polymer having perfluorocyclobutane rings by the steps of (a) contacting monomers having at least two dimerizable perfluorovinyl groups; and (b) exposing the monomers to sufficient heat and for a sufficient time that a polymer containing perfluorocyclobutane rings is formed wherein at least about 0.05 mole percent of the monomer, have at least 3 dimerizable perfluorovinyl groups and polymers prepared thereby.
