Claimed: A process for the preparation of monomeric, oligomeric and polymeric non-, partially or perfluorinated sulfonic acids by reacting halogenated low molecular weight, oligomeric or macromolecular arenes with (hydrogen) sulfites, dithionites, sulfides or other reducing sulfur salts, optionally under oxidation resulting sulfur-containing arene intermediate compounds with lower Oxidation stage of sulfur as +6 with suitable oxidants to form the corresponding sulfonate functional groups (sulfonic acid groups, sulfohalide groups, sulfonamide groups, sulfonic acid ester groups). Process for the preparation of monomeric, oligomeric or polymeric non-, partially or perhalogenated phosphonic acid esters and their derivatives (eg free phosphonic acid or phosphonic acid salt) by means of nucleophilic aromatic substitution (Michaelis-Becker reaction), partial or complete replacement of the halide functional groups by phosphonate functional groups (phosphonic acid esters, phosphonic acid amides, phosphonic acids, phosphonic acid salts, phosphonic acid halides). · Method for producing non-, partially or perhalogenated, (CF 2 ) x PO (OR) 2 - or (CF 2 ) x SO 2 ME- or (CF 2 ) x SO 3 Me side chains (x = 1-20 , R = any organic radical, Me = any monovalent cation) containing polymers or ionomers. · Process for the nucleophilic polycondensation of the mentioned functionalized (ie ... |
