    Abstract: A problem is to provide a monolithic structure that is a porous body formed of a polysaccharide being a naturally-occurring polymer, and has continuous pores having an average pore diameter suitable for biomolecule separation to allow formation into an arbitrary shape, and a manufacturing method therefor. A solution is to manufacture the polysaccharide monolithic structure by a method including a first step for dissolving a polysaccharide into a mixed solvent including a solvent into which the polysaccharide is soluble and a solvent into which the polysaccharide is insoluble, at a temperature lower than a boiling point of the mixed solvent, to give a polysaccharide solution, and a second step for cooling the polysaccharide solution to give the polysaccharide monolithic structure. The polysaccharide monolithic structure obtained is a porous body having continuous pores having an average pore diameter of 0.01 to 20 micrometers and a thickness of 100 micrometers or more.

    Abstract: A process for producing a porous body with different physical properties in desired regions is provided by pore forming treatment, not by bonding two or more materials made porous beforehand, with, for example, an adhesive. Raw materials are prepared, each of which contains a polymer and a raw material preparation solvent. At least two types of the raw materials having different compositions are prepared. Thereafter, the respective raw materials are frozen into desired shapes to form frozen bodies thereof. The frozen bodies thus formed are brought into contact with each other to form an assembly thereof, the assembly is exposed to a condition under which the frozen bodies begin to melt, and the assembly is then freeze-dried. Thus, a porous body having regions different in physical properties can be obtained. Such a porous body can be used as, for example, an adhesion inhibitory material or a scaffold for a cell culture.

    Abstract: It is proposed to use a synthetic granulate or powder with a particle size of 0.1 to 10 mm as packing material for the removal of liquid, gaseous and/or dissolved constituents from a process stream, which packing material is made up of a porous, preferably dimensionally stable polymer having an overall porosity of 50 to 95% by volume, which when used as an extracting medium has pores of a diameter of 0.01 to 50 .mu.m, with an extracting liquid immobilised therein, or when used as a coalescence medium has a cellular body/window structure with the diameter of more than 50% by volume of the bodies being in the range of 100 to 700 .mu.m, which materials can be obtained by dissolving a polymer in one or more liquid and miscible compounds at a temperature above the upper critical phase separation temperature Tc, followed by a lowering of the temperature and mechanical diminution of the polymer filled with the liquid compounds, optionally followed by removal of the liquid therefrom and, optionally, refilling of at least 10% of the pore volume with an extracting liquid, characterised in that the polymer solution incorporates 5 to 60% by volume of filler, calculated on the overall solids content. The granulate or powder preferably is subjected to an aftertreatment by being coated with a powder or fibrous material having a softening temperature or melting temperature higher than that of the material to be coated.
