Abstract
A process for the preparation of a porous composite product. The process steps are forming a homogeneous mixture having one or more insoluble polymers, one or more soluble or calcinable polymers and one or more fillers, in particular with a high specific surface; extruding the mixture to form an extruded precursor product; removing the soluble or calcinable polymer or polymers from the extruded precursor product, in order to form pores, and recovering the porous composite product.
