摘要： In this work, the condition for the analysis of title compounds by HPLC was chosen.The componentcontent and average molecular weight of some kinds of poly(ether-sulfone)s oligomers were determined suc-cessfully. The optimum condition for the partial hydrolysis reaction from 4,4'-dichlorodiphenylsulfone to 4-chloro-4'-hydroxyldiphenylsulfone was obtained.In addition,the constituent changes of the oligomer can beobserved and determined by this method in the polymerization process.
