OLIGOMERS AND POLYMERS CONTAINING SULFONITE GROUPS AND METHOD FOR THE PRODUCTION THEREOF

WIPO Patent Application WO2003022892

A3

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, C1, 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.
