The invention relates to novel polymers or oligomers containing at least sulfonite groups (P—(SO2)nX, X=1−(n=1), 2−(n=2) or 3−(n=3) valent metal cation or H+ or ammonium ion NR4+ where R=alkyl, aryl, H), which are obtained by completely or partially reducing polymers or oligomers containing at least SO2Y-groups (Y═F, Cl, Br, I, OR, NR2 (R=alkyl and/or aryl and/or H), N-imidazolyl, N-pyrazolyl) by means of suitable reducing agents in a suspension or in a solution form. The invention also relates to polymers and polymer(blend) membranes which are obtained by further reacting the obtained sulfinated polymers, especially by alkylation of the sulfinate groups with mono- di- or oligo functional electrophiles. The invention further relates to methods for producing the sulfinated polymers and for further reacting the sulfinated polymers with electrophiles by S-alkylation.
At least sulfinate group (P—(SO2)nX, X=1−(n=1), 2−(n=2) or 3−(n=3) valent metal cation or H+ or ammonium ion NR4+ with R=alkyl, aryl, H) containing polymer or oligomer in the volume or at the surface, characterized in that it is obtained by a complete or partial reduction of a polymer or oligomer containing SO2Y (Y═F, Cl, Br, I, OR, NR2 (R=alkyl and/or aryl and/or H), (N imidazole, N pyrazole) by means of suitable reducing agents in suspension or in solution either in the volume or superficially.
