The present invention relates to a process for modifying an aromatic polyether backbone for obtaining a modified polyether comprising the steps of: a) providing the at least one aromatic polyether to be modified in dissolved state in an inert organic solvent, b) adding at least one modification reagent, c) adding at least one catalyst, d) carrying out the process until a desired degree of functionalization of said aromatic polyether backbone is reached, e) recovery of the modified aromatic polyether. The present invention also relates to a modified polyether obtained by this process.
