Amines or salts thereof and methods of preparing same

A salt of an amine compound, said amine compound having a fluorocarbon sulfonic acid ester group and represented by the formula —[HN—SO2ORf4OSO2]m—, said salt having said fluorocarbon sulfonic acid ester group and represented by the formula —[M[N-SO2ORf4OSO2]n]m—,

• wherein said salt is prepared by a method comprising:
• (a) reacting a bis(chlorosulfonyl)amine represented by the formula HN(SO2Cl)2 with a fluorodiol represented by the formula HORf4OH, to prepare said amine compound,
• (b) reacting said amine compound with a third compound, to prepare said salt, said third compound comprising M,
• wherein Rf4 represents a fluorine-containing bivalent organic group which has from 3 to 18 carbon atoms and consists of at least one of a straight-chain portion, a branched-chain portion and a ring chain portion, and an optional unsaturated bond and an optional oxygen atom,
• M represents a positive ion which has a valence and is selected from the group consisting of ions of ammonium, quaternary ammonium, alkali metals, alkali earth metals, transition metals, rare earth elements, aluminum, gallium, iridium, thallium, tin, lead, arsenic, antimony, and bismuth;
• n represents an integer that is the same as said valence;
• and
• m represents an integer from 1 to 1,000.
