Abstract
The invention relates to a novel and inexpensive process for the nitration and amination of aryl polymers and also to their use as blend components for producing polymer blend membranes. Such polymer blend membranes are used in membrane processes, in particular as polymeric electrolyte in electromembranes, e.g. for electrodialysis and fuel cells.
