The invention relates to producing monomer, oligomer and polymer non-fluorinated, partially fluorinated or perfluorinated sulphonic acids by reacting halogenated, low-molecular weight, oligomer or macromolecular arenes with (hydrogen) sulphites, dithionites, sulphides or other reducing sulfur salts, possibly by oxidising sulphur-containing arene intermediates which are formed at a sulphur oxidation degree less than +6 by means of appropriate oxidation agents with formation of corresponding sulphonate functional groups (sulphonic acid, sulfohalogenide, sulphonamide and sulphonic acid ester groups). The invention also relates to a method for producing monomer, oligomer or polymer non-halogenated, partially halogenated or perhalogenated phosphonic acid esters and the derivatives thereof (for example, a free phosphonic acid or a phosphonic acid salt) by a nucleophile aromatic substitution (Michaelis-Becker-reaktion, complete or partial substitution of halogenide functional groups by phosphate functional groups (phosphonic acid esters, phosphonic acid amides, phosphonic acids, phosphonic acid salts, phosphonic acid halogenides). Said invention also relates to a method for producing polymer or ionomer non-halogenated, partially halogenated or perhalogenated containing (CF2)xPO(OR)2- or (CF2)xSO2Me- or (CF2)xSO3Me- side chains, (wherein x = 1 - 20, R = any organic radical, Me = any monovalent cation). A method for carrying out a nucleophile polycondensation of said functionalised (i.e. sulphonated, sulphonated or phosphonated) monomers into oligomers or polymers is also disclosed.
