ABSTRACT:
Long chain-perfluoroalkylene ether bibenzoxazole polymers are synthesized by the polycondensation of long chain-perfluoroalkylene ether bis(o-aminophenol) compounds and perfluoroalkylene ether diimidate esters. The elastomeric polymers have a combination of high thermooxidative stability and superior low temperature visco-elastic properties that render them particularly useful for wide temperature range applications, such as seals, sealants and the like.
