Abstract: COMPOUNDS OF THE FORMULAS

CH3-OOC-(CF2)(2,3)-NO, AND (CH3-O-CO-(CF2)(2,3))2-N-O-

(CF2)(2,3)-COO-CH3

ARE PRODUCED BY REACTING METHYL NITRITE AND PERFLUOROGLUTARIC ANHYDRIDE OR PERFLUOROSUCCINIC ANHYDRIDE AND THEN DECARBOXYLATING THE RESULTANT PRODUCT. THE COMPOUNDS, WHICH CAN BE HYDROLYZED TO PRODUCE THE CORRESPONDING NITROSO-SUBSTITUTED FLUOROCARBON ACIDS, ARE USED AS COMONOMERS IN NITROSO RUBBERS.
