摘要:
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 Formula (II), 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. The compound is preferably prepared by a process of thermally dimerizing a trifluorovinyl compound to form a compound of the following 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 perfluorocyclobutane group.
