4,4'-Dichlorophenylsulfone homopolymer with potassium hydroxide is a specialty polymeric intermediate and ion-containing polymer material. It is mainly used in the preparation of high-performance polymers, ion exchange materials, polymer electrolyte membranes, specialty coatings, and chemical-resistant engineering materials. The material can serve as a precursor for polymer modification and functional polymer synthesis due to its aromatic sulfone backbone and alkali-reactive groups.
