Embodiment Construction
[0006] A method for preparing dearomatized resin balls, the specific steps are as follows: under the action of nitrogen, take styrene monomer and add it to a solvent, add a catalyst and triethylamine, drop a mixed solution of a sulfonating agent and a solvent, and use a column layer Separating and purifying the product by chromatography to obtain sulfone-containing styrene monomer, adding styrene monomer and sulfone-containing styrene monomer to the reaction device, using polyvinyl alcohol aqueous solution as a solvent, feeding nitrogen, and adding a cross-linking agent , The molar ratio of cross-linking agent to styrene monomer is 1:50-100; react to obtain solid balls, filter to obtain resin balls, add resin balls to a mixed solvent of tetrahydrofuran and dilute hydrochloric acid, and filter to obtain resin balls.
