PCT No. PCT/SE93/00226 Sec. 371 Date Sep. 16, 1994 Sec. 102(e) Date Sep. 16, 1994 PCT Filed Mar. 16, 1993 PCT Pub. No. WO93/19115 PCT Pub. Date Sep. 30, 1993Porous material of a polysaccharide and a method for preparations of such a material, wherein a water-based solution of the polysaccharide is mixed, with controlled stirring, with an essentially water-immiscible organic phase to form an emulsion, which when allowed to solidify, just before or during the gelling process, forms a network of two continuous phases, an aqueous polysaccharide phase and a flow-pore-forming organic phase, resulting in a material with two types of pores: small diameter diffusion pores and large diameter flow through pores. |
