PROBLEM TO BE SOLVED: To provide a method for producing monomer, oligomer and polymer of phosphonic acid esters and phosphonic and sulphonic acids by a nucleophile aromatic substitution.SOLUTION: This invention relates to a method for producing monomeric, oligomeric and polymeric (perfluorinated) sulfonic acids by reaction of halogenated low-molecular, oligomeric or macro-molecular arenes with (hydrogen) sulfites, dithionites, sulfides or other reducing sulfur salts, and if possible, with an oxidation state of the sulfur lower than +6, and with suitable oxidation reagents, by oxidation of sulfur-containing arene intermediate compounds formed together with formation of the corresponding sulfonated functional groups (sulfonic acid groups, sulfohalogenide groups, sulfonamide groups, sulfonic acid ester groups). This invention further relates to a method for producing monomeric, oligomeric and polymeric phosphonic acid ester as well as their derivatives by nucleophilic aromatic substitution, and by part or complete substitution of the halogenide functional groups by phosphonate functional groups.SELECTED DRAWING: None |
