Abstract:
A process comprising: contacting in a liquid dispersion or solution a composition comprising a metal sulfonyl amide salt represented by the formula:R2SO2NMb wherein R2 is aryl, fluoro-aryl, or XCF2â€” where X is H, halogen, fluorinated or non-fluorinated linear or cyclic alkyl radicals having 1-10 carbons, optionally substituted by one or more ether oxygens, b=1 or 2, M is an alkaline earth where b is 1 or an alkali metal where b is 2; with a non-polymeric sulfonyl fluoride composition represented by the formula, R1(SO2F)m wherein m=1 or 2, where when m=1, R1 is a fluorinated or non-fluorinated, saturated or unsaturated hydrocarbyl radical except perfluoroolefin having 1-12 carbons optionally substituted by one or more ether oxygens, or tertiary amino; or, when m=2, R1 is a fluorinated or non-fluorinated, saturated or unsaturated hydrocarbylene, except perfluoroalkylene, radical having 1-12 carbons optionally substituted by one or more ether oxygens; or with a polymeric sulfonyl fluoride composition comprising monomer units represented by the formula:â€”[CZ2CZ(R3SO2F)]â€”wherein R3 is a diradical selected from the group consisting of fluorinated or non-fluorinated alkenyl, including oxyalkenyl or fluorooxyalkenyl, and each Z is independently hydrogen or halogen, and need not be the same; and, causing them to react to form a non-polymeric imide composition represented by the formula:R1(SO2NMbSO2R2)m or, in the alternative, a polymeric imide composition comprising monomer units represented by the formula, (â€”[CZ2CZ(R3SO2N(M)SO2R2)]â€”)y.
