Abstract

A process is provided for forming a polymeric material which can be developed into a shaped polymeric structure comprising an active material encradled in a porous, fiber-containing polymeric composition. In the process, the active material is mixed with a tripartite system comprising a fibrillatable polymer, a support-contributing polymer and a pore-former. When such a system is mixed and developed with an active material, such as LaNi.sub.5, an active composition is produced which may be used, for example, as a hydrogen collecting or storing material.
