POLYMER COMPOSITION, MEMBRANE CONTAINING SAID COMPOSITION, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

Disclosed is a composition containing 30-95 wt.% sulphonated aromatic polyether ketone with an ion exchanger capacity of 1.3-4.0. meq (-SO3H)/g polymer, and 0.5-70 wt.% polybenzimidazol. The inventive composition can be processed into membranes like the PEK-type of sulphonated polyether ketone. Preferably, said membranes are used in fuel cells.
