Abstract
An organic-inorganic hybrid is derived from combining at least one inorganic alkoxide and a hydrogenated sulfonated block copolymer containing a controlled distribution copolymer block of a conjugated diene and a mono alkenyl arene, where the controlled distribution copolymer block has terminal regions that are rich in conjugated diene units and a center region that is rich in mono alkenyl arene units. The inorganic alkoxide may be an alkoxysilane compound or composition.
