The present invention pertains to a resin composition which includes component: a membrane-forming polymer, component: a polymer obtained by polymerizing a monomer composition which includes a (meth)acrylic ester macromonomer represented by general formula and another monomer, and component: a polymer including a vinylpyrrolidone unit, a membrane-forming stock solution which includes the resin composition, a porous membrane obtained by forming with the membrane-forming stock solution, and a hollow fiber membrane, a water treatment device, an electrolyte support, and a separator which use the porous membrane. According to the present invention, it is possible to provide a porous membrane which has pores with high uniformity wherein the formation of large pores with a diameter of 1 m or higher is suppressed and which has excellent fractionation performance and high water permeability, and a hollow fiber membrane, water treatment device, electrolyte support, and separator which use the porous membrane.

Provided are filtration media and matrixes comprising a pulverized powder of ion exchange resin and a polymeric binder. The resin can be pulverized to an average particle size in the range of 50 to 250 microns and can comprise a cation exchange resin, an anion exchange resin, a chelating resin, a biologically-related ion exchange resin, or combinations thereof. The media can further comprise activated carbon. The binder can be ultra high molecular weight polyethylene. The filtration media can be used to make matrixes and systems. Methods of making and using the same are also provided.

An X-ray amorphous magnesium carbonate is disclosed that is characterized by a cumulative pore volume of pores with a diameter smaller than 10 nm of at least 0.018 cm.sup.3/g, and a specific surface areas of at least 60 m.sup.2/g. The X-ray amorphous magnesium carbonate is produced by reacting an inorganic magnesium compound with alcohol in a CO.sub.2 atmosphere. The X-ray amorphous magnesium carbonate can be a powder or a pellet and acts as a desiccant in, for example, production of food, chemicals or pharmaceuticals.
