Functionalizing polyarylethersulfones with basic groups, for use in electrolytes, ion exchangers, catalysts, polymer electrolyte membranes or blends, involves a Grignard reaction and reaction with an anchoring compound

摘要

A bisphenol A polyarylethersulfone carrying a basic group is obtained by halogenating an unsubstituted polyarylethersulfone, followed by reacting with a metal and then with an anchoring compound containing a basic group. A polyarylethersulfone of formula (I) carrying a basic group is obtained by halogenating an unsubstituted polyarylethersulfone of formula (II), followed by reacting with a metal and then with an anchoring compound of formula (X-A-B) m. X : a removable group; A : an anchoring group; B : a basic group; and m : 1, 2 or 3. [Image] [Image].
