| description | A sulfonated heat-resistant polymeric material containing at least 1 % by weight (in terms of sulfur content) of sulfone groups and an ammonia adsorption capacity of at least 10 mg/g, which is produced by heat-treating at 250 to 500 DEG C a starting material composition mainly comprising a sulfonated aromatic polymeric compound containing an aromatic sulfonic acid or its salt as the repeating unit and being soluble in aqueous solvents.
On produit un matériau polymère thermorésistant sulfoné, qui contient au moins 1 % en poids (en termes de teneur en soufre) de groupes sulfone et qui présente une capacité d'adsorption de l'ammoniac d'au moins 10 mg/g, en soumettant à un traitement thermique à une température comprise entre 250 et 500°C une composition d'un matériau de départ comprenant essentiellement un composé polymère aromatique sulfoné, qui contient un acide sulfonique aromatique ou son sel comme unité de répétition et qui est soluble dans des solvants aqueux. |
