ABSTRACT:
Inorganic-organic composites suitable for use as separators in alkaline storage batteries requiring gas permeability, thermal stability, chemical stability and good structural strength and a process for making them are disclosed. The composites are more thermally stable prior art separator materials, retain aqueous alkaline electrolytes well and are chemically resistant to 31% KOH solutions at 110.degree. C.
