ABSTRACT:
Hexafluoropropylene oxide-terminated perfluoroalkylene ether-imidate and -thioimidate esters are prepared by the reaction of certain perfluoroalkylene ether dinitriles with trifluoroethanol or ethanethiol. The compounds are useful as monomers in synthesizing thermooxidatively stable, low glass transition temperature perfluoroalkylene ether bibenzoxazole polymers with improved hydrolytic stability properties.
