ABSTRACT:
Two new organic compounds are disclosed, perfluorocyclohexane-1,4-dione and perfluorocyclohexene-1,4-dione, which are obtained concurrently or alternatively by reacting fluoranil with substantially pure anhydrous cobalt trifluoride. These compounds are clear, colorless liquids which are useful as monomers in the synthesis of thermally stable elastomeric polymers. Also disclosed is the dihydrate of said perfluorocyclohexane-1,4-dione, namely, octafluoro-1,1,4,4-cyclohexanetetraol. Another aspect of this invention is a series of polyethers formed by reacting said perfluorocyclohexane-1,4-dione with cesium fluoride and a cyclic or noncyclic aliphatic perhaloalkene having from 2 to 12 carbon atoms and a fluorine atom on at least each of the carbon atoms connected by the double bond, said polymer having as a repeating unit ##SPC1##
