    摘要: ALKYL ESTERS OF PERFLUOROALKYL ALKYLENE THIOCARBOXYLIC ACIDS ARE DISCLOSED WHEREIN THE ACIDS ARE REPRESENTED BY THE STRUCTURES:

    RF-(CH2)N-S-C(-R)(-CH(-R)-COOH)-COOH (I)

    RF-(CH2)N-S-CH(-CH2-COOH)2 (II)

    RF-CH2-S-CH2-CH(-COOH)-CH(-R)-COOH

    WHEREIN RF IS PERFLUORALKYL, N=1-3, AND R IS H, CH3, OR C2H5, AND WHERE IN FORMULA I AT LEAST ONE R IS H. THE ESTERS ARE READILY CONVERTED TO THE ACIDS WHICH ARE USEFUL FOR IMPARTING OIL AND WATER REPELLENCY TO LEATHER.

    摘要: Cis and trans-1-trifluoromethyl-1,2,2-trifluoro-4methylcyclobutane and mixtures thereof are provided. These compositions are liquids having high dielectric constant and low freezing points, useful as working fluids for hydraulic systems and as inert solvents. Also provided are linear dimers, 4,4,5,6,6,6-hexafluorohexene-1 and 4,4,5,6,6,6-hexafluorohexene2, useful as comonomers in ethylene and propylene polymerization.
