Abstract: front page image
(EN)Provided herein are imidazolium polymers having steric hindrance at the 4-position of the imidazole moieties in the polymeric chain. The sterically-protected, N-methylated imidazolium polymers exhibit hydroxide stability in concentrated caustic solutions at elevated temperatures, such as at 100 °C and higher.
(FR)L'invention concerne des polymères d'imidazolium ayant un encombrement stérique à la position 4 des fractions d'imidazole dans la chaîne polymérique. Les polymères d'imidazolium N-méthylés à protection stérique présentent une stabilité à l'hydroxyde dans les solutions caustiques concentrées à des températures élevées, comme 100°C et plus.
