A hydrogen sorbent composition is provided which is comprised of a hydridable material such as LaNi.sub.5 encradled throughout a porous, fiber-containing polymeric composition.

Hydrogen sorbent composition

An improvement in the production of polymer-bonded cell electrodes comprises forming a particulate material which can be developed into a shaped polymeric system comprising an electrode active material encradled in a porous, fiber-containing, polymeric composition. In a preferred embodiment, the polymeric system is developed as a thin, flexible electrode.

Production of a cell electrode system

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.

Production of a polymeric active composition

A particulate catalyst composition is provided by processing components in standard polymer processing equipment to obtain catalyst particles encradled in a porous, fiber-containing polymeric material.

Particulate catalyst and preparation

A catalyst composition is provided as a thin flexible sheet in standard polymer processing equipment. The catalyst is comprised of catalyst particles encradled in a porous, fiber-containing polymeric material.

Catalyst sheet and preparation

A material useful as a separator in batteries and a process for making the material is provided. This material is a polyolefin having grafted to it side chains derived from an ethylenically unsaturated ionogenic monomer and cross-linked with sulfur.

Material for an alkaline cell separator and a process of making

A process for preparing a polymeric material grafted throughout its bulk is provided. A polymer having finely divided particles is blended with silica and maintained in a fluidized bed. The polymer is activated by passing ozone uniformly through the blend to initiate incipient labile sites in the molecular structure of the polymer. The polymer is then reacted with an ethylenically unsaturated ionogenic monomer to graft polymerize the monomer onto the polymer. The grafted polymer may then be converted to a salt form by reacting with alkaline compounds. The resultant powders can be fused into any desired shape by conventional polymer plastic processes.
