Abstract (en)
[origin: DE102005052378A1] A method (M1) for the production of high-molecular weight polymers with phosphonic acid groups (A) by radical polymerisation of a composition (I) containing at least 80.0 wt.% ethylenically-unsaturated compounds (II), in which composition (I) contains at least one monomer (III) with phosphonic acid groups. Independent claims are included for (1) a method (M2) for the production of high-molecular weight polymers with sulfonic acid groups (A) by radical polymerisation of a composition (I) as above which contains at least one monomer (IV) with sulfonic acid groups; (2) polymers (A) obtained by M1 or M2, with a degree of polymerisation (weight-average) of more than 300; (3) compositions containing (A) and a different polymer (B); (4) membrane-electrode units (MEU) comprising two electrodes in contact with catalyst layers and separated by a polymer-electrolyte-membrane containing (A); and (5) fuel cells with at least one MEU as above.
