Fluorocarbon bis(o-aminophenol) compounds in which fluoroalkylene groups attached to each aminophenol radical are separated by a hydrocarbon moiety. The compounds are useful as monomers in preparing thermooxidatively and hydrolytically stable, low glass transition temperature perfluoroalkylene ether bibenzoxazole polymers containing hydrocarbon cure sites.
