Sulfonated poly (aryl ether ketone ketone) (S PEKK) was prepared by sulfonating poly (aryl ether ketone ketone) with sulfuric acid as sulfonating agent.The effects of sulfuric acid concentration and reaction temperature on the sulfonation degree of poly (aryl ether ketone ketone) , And the sulfonated poly (aryl ether ketone ketone) was characterized by infrared spectroscopy, X-ray diffraction and DSC, and the catalytic activity of sulfonated poly (aryl ether ketone ketone) in the synthesis of ethyl acetate and butyl acetate was also investigated. The results showed that S PEKK has good catalytic activity, can be recycled and so on.
