Abstract
Abstract A polymeric structure comprising particles of a hydridable material encradled in a porous, fibre-containing polymeric material is disclosed. The structure is prepared by dry processing the hydridable material, a removable pore-forming material and a fibrillatable polymer to fibrillate the latter and form a homogeneous mixture. The pore-forming material is then removed. Preferably, the fibrillatable polymer is converted to fibres in the presence of the other components of the mixture.
