Thermally Stable Perfluoroalkylene Ether Bibenzoxazole Polymers.
Abstract
The patent application concerns perfluoroalkylene ether bibenzoxazole polymers, thermally stable at elevated temperatures, which are prepared by the condensation of a perfluoroalkylene ether bisaminophenol and a perfluoroalkylene either diimidate. Because of the high thermal stability and low glass transition temperatures of the polymers, they are eminently suitable for use in aerospace applications where a wide range of temperature conditions is encountered. In particular, the polymers are useful as sealants and seals.
