Beschreibung
Zusammenfassung:	This invention relates to a silane-resin composition that can be obtained by at least partial hydrolytic condensation of at least the following components: (1) one or more sulfonic acid group-containing silane(s) with at least one group that can be cleaved under hydrolytic conditions, (2) one or more styryl-functionalized silane(s) and (3) one or more silane(s) that carry a nitrogen-containing heterocyclic compound, an amine group or a sulfonamide group with at least one group that can be cleaved under hydrolytic conditions, and mixing of the components before, during or after the hydrolytic condensation, as well as a process for the production of this composition. With the silane resin that is obtained, proton-conductive, organically cross-linked heteropolysiloxanes can be produced that are suitable for PEMFC in a layer or membrane form as proton-conductive systems. Their proton conductivity can be further increased by the addition of suitable liquids.
