| titleOfInvention | Proton Conducting Copolymers |
| abstract | The present invention relates to proton conducting copolymers, preferably proton conducting block copolymers, according to formula (I) wherein the copolymer comprises 2,5- and/or 2,6-di(p-R 1 -aryl)phenol moieties and 2,5- and/or 2,6-di-R 2 -phenol moieties; R 1 is hydrogen or a C 1 -C 10 alkyl group; R 2 is a C 1 -C 10 alkyl group; and R 3 is chloro, bromo or a heterocyclic group selected from 1-pyrazolyl, 1-benzopyrazolyl, 1-imidazolyl, 1-benzoimidazolyl, 2,3-triazol-1-yl, 2,4-triazol-1-yl, 1,6-dihydropyridazin-1-yl, 1,2-dihydropyrimidin-1-yl, 1,2-dihydro-1,3-benzodiazin-1-yl, 1,2-dihydropyrazin-1-yl, 1,2-dihydro-1,4-benzodiazin-1-yl, 1,2-dihydro-1,3,5-triazin-1-yl and 3,4-dihydro-1,2,4-triazinyl, provided that within the copolymer at least one R 3 is a heterocyclic group; p is in the range of 100 to 100.000; and q is in the range of 100 to 100.000. The proton conducting copolymers are very suitable as membranes for fuel cells. |
