TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: (I) is prepared by reacting a hydroxylic organic precursor (e.g. an alcohol or phenol) or an aminic organic precursor (e.g. an amine or aniline) with a sulfonyl halide in an aprotic solvent. The reaction is carried out in a molar excess of tertiary amine to consume the hydrogen halide acid generated at a temperature of approximately 0-25 degreesC. The triethylammonium salt obtained is filtered and, to exchange with the desired cation, neutralization is conducted with an aqueous solution or dispersion of the base. Water is removed, and the resulting solid is washed with a water-immiscible solvent and purified on an alumina column.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Electrolyte: The electrolyte additionally contains one or more conductive salts. The total salt concentration in the matrix material is from about 0.1M to 2M.    TECHNOLOGY FOCUS - POLYMERS - Preferred Polymer: The polymerizable group is an olefinically unsaturated group, an epoxide group and/or an isocyanate group (preferably vinyl, allyl or (meth)acrylyl). Preferred Definitions:    R = CH3-, C2H5-, (CH3)2CH-, (CH3)3CCH2-, C8H17-, C6H5-, C10H7-, H3CC6H4-, O2NC6H4-, FC6H4-, NCC6H4-, (CF3)2C6H3-, CH2=CH2-, CH2=CHCH2-, CH2=C(CH3)-, CH2=CHC(O)OC2H4-, CH2=C(CH3)C(O)OC2H4-, CH2=CH-C6H4-, HC-triple bond-CCH2-, OCN(CH2)6NH-, OCN-C6H4-, HOC2H4-, HOCH2CH(OH)CH2-, H2NC2H4-, (CH3O)3SiC3H6-, (CH3O)2(CH3)SiC3H6-, 2-methylene oxirane or 2-methyleneaziridine;    R' = R, CF3-, C2F5-, C4F9-, C8F17-, (CF3)2NC2F4-, CF3OC2F4-, perfluorocycloalkyl or perfluorocycloalkylfluoroethyl;    Mn+ = lithium;    Q = N, O or S;    p = 2; and    o = 1 or 2.    The two R groups may form a member selected from -CH2CH2-, -CH2CH(CH3)-, -CH2=CH-C6H4-, disubstituted phenyl and 2,2'-biphenyl. R and R' may together form an alkylene group or a phenylene group joined at the 1,2-positions to form a ring.    SPECIFIC COMPOUNDS - 5 compounds of formulae (II) - (VI) are specifically claimed as the sulfonylimide salts.    EXAMPLE - Imidobis(sulfuryl chloride) (42 g) was added to a mixture of catechol (17 g) and anhydrous acetonitrile (75 g) to obtain a solution which was cooled to 0 degreesC. To this solution was added anhydrous triethylamine (85 g) dropwise with stirring for 1 hour to obtain an oil. This oil was neutralized with aqueous LiOH (1M) and the water was removed to obtain a solid which was purified in tetrahydrofuran over a column of basic alumina. The conductivity measurement of the solid (0.8 M) was found to be 7.2 milli-siemens per square centimeter.
