| titleOfInvention | Method for sulfonating block polymers |
| abstract | An improved method for preparing sulfonated block polymers with acyl sulfate in non-halogenated aliphatic solvents is provided. The method includes sulfonating a precursor block polymer with acyl sulfate in a reaction mixture further comprising at least one non-halogenated aliphatic solvent to produce a sulfonated block polymer, wherein the precursor block polymer The initial concentration of polymer ranges from about 0.1% by weight to a concentration below the critical concentration of the precursor block polymer, based on the total weight of the reaction mixture. A degree of sulfonation greater than about 1.0 milliequivalent of sulfonic acid per gram of sulfonated block polymer can be achieved without substantially causing precipitation of the polymer and without causing gelation to become unprocessable. |
