(US6025092-A)   NOVELTY - Fluorinated but not perfluorinated ionomers with a polyethylene backbone and pendant fluoroalkoxy sulfonic acid and sulfonic acid salt groups provide a solution to the long-standing problem of obtaining ionomers comprising monomer vinylidene fluoride (VDF) units resistant to attack by bases.    USE - The ionomers are useful in electrochemical applications, e.g. batteries, fuel cells, electrolysis cells, ion exchange membranes, sensors, electrochemical capacitors, and modified electrodes.    ADVANTAGE - In contrast to previous ionomers, the new ionomers in combination with preferably 50 - 200 wt.% of solvents suitable for electrochemical applications, especially lithium batteries, show good melt processability with no decrease in optimum battery performance.
