    Abstract: Supercritical drying has distinct advantages in generating microcellular materials. The dimensional stability of the polymer is not affected on drying because the supercritical process does not go through the two phase path and therefore the effect of capillary forces is absent. This helps in maintaining the morphology of the final polymer structure and better control over cell size. Organic microcellular foams were prepared by polymerizing directly in a near-critical fluid and pursuing the supercritical drying in the same reactor. The critical variables are the choice of a diluent with a strong enough solvent power to stabilize the polymer matrix, but with a low enough critical temperature to permit critical point drying without damage to the polymer matrix.

    Abstract: A method of preparing a porous membrane which includes the steps of dissolving a thermoplastic material which has both relatively non-crystalline and relatively crystalline portions into a solvent under conditions of temperature and time which cause the relatively non-crystalline portions of the thermoplastic to dissolve while at least a portion of the relatively crystalline portions of said thermoplastic material do not dissolve, but form a colloidal dispersion in said solvent. The colloidal dispersion and solvent are formed into a film, thereafter causing precipitation of the dissolved thermoplastic portions in the said film, to form a porous membrane.

    Abstract: A method for the manufacture of a solid porous separation material based on a polysaccharide, said method comprising the steps of: (a) providing an aqueous solution (I) of a polysaccharide, (b) solidifying the solution, preferably by transforming the solution to a gel, and (c) optionally crosslinking the polysaccharide, with the proviso that, if step (c) is present, steps (b) and (c) may be carried out simultaneously. The method is characterized in that the polysaccharide provided in step (a) is modified by being inter-molecularly crosslinked to an extent such that the viscosity of the solution (I) is at least 110%, preferably at least 200%, of the viscosity of an aqueous solution (II) of the corresponding polysaccharide which has not been intermolecularly crosslinked and which is present in the same concentration as the inter-molecularly crosslinked polysaccharide is in solution (I)
