    摘要: 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+ wherein 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.

    摘要: The invention relates to a membrane for proton conduction, made of a proton-conducting polymer for use in redox flow batteries. The polymer is sulfonated poly(ether ketone ether ketone ketone) (PEKEKK). The membranes are efficient, mechanically stable, oxidation-resistant in VO2+ with sulfuric acid, and exhibit long-term stability in the unblended state. The membranes can be used for several hundred to a thousand hours in vanadium redox flow batteries having black start capacity. Formula I, PEKEKK with a sulfonic acid group and an IEC of 1.73 meq/g.
