Method for producing sulfonated styrene polymer |
| abstract |
(57) Abstract: To provide an efficient method for producing a sulfonated styrene polymer having a small amount of by-product sulfate. SOLUTION: The styrene-based polymer is sulfonated by introducing the sulfonating agent into a solvent which is inactive to the sulfonating agent prepared by dissolving the styrene-based polymer. A method for producing a styrene-based polymer sulfonate, which comprises adding one or more alcohols, amines, or an electron-donating group-containing aromatic compound. |
