MODIFIZIERTES POLYMER UND MODIFIZIERTE POLYMERMEMBRAN

摘要

The present invention provides novel, economic processes for preparing nitrated and sulfonated polymers and aminated and sulfonated polymers. Also provided are the polymers prepared by these processes. The invention also provides for membranes comprising the polymers, methods for preparing the membranes and their use in electromembrane processes, particularly in fuel cells.
