摘要： Improved methods for preparing sulfonated block polymers with acyl sulfates in non-halogenated aliphatic solvents are provided. The methods include the sulfonation of a precursor block polymer with an acyl sulfate in a reaction mixture further comprising at least one non-halogenated aliphatic solvent to form a sulfonated block polymer, wherein the initial concentration of the precursor block polymer is in the range of from about 0.1 wt % to a concentration that is below the limiting concentration of the precursor block polymer based on the total weight of the reaction mixture. A sulfonation degree of greater than about 1.0 milliequivalent sulfonic acid per gram sulfonated block polymer can be achieved substantially free of polymer precipitation and free of disabling gelation.

摘要： The present invention relates to an improved method for making sulfonated block copolymers and to methods for making membranes from such block copolymers. In particular, the present invention relates to an improved method for making sulfonated block copolymers having at least two polymer end blocks that are resistant to sulfonation and at least one polymer interior block that is susceptible to sulfonation where the sulfonation agent is C2 to C8 acyl sulfate. In the improved process the residual carboxylic acid formed from the C2 to C8 acyl sulfate is converted to C1 to C4 alkyl esters by contacting the residual carboxylic acid with at least a 0.9:1 molar ratio of a C1 to C4 alcohol to residual carboxylic acid, resulting in an improved sulfonated block copolymer solution. The present invention further relates to the use of such sulfonated block copolymer solutions to prepare various membranes and other articles.
