Abstract: PURPOSE:To obtain the title molded item having excellent pressure resistance and being especially suitable for instrumental analyses such as ionic liq. chromatography, by providing ion exchange groups on the inner wall face of a hollow molded item made of an org. polymer. CONSTITUTION:The title molded item is a hollow molded item made of an org. polymer (when a liq. is passed through the inside of the hollow molded item, it is pref. that the liq. neither permeates through nor breaks the inner wall and the inner diameter is 10-3,000mu) and has ion exchange groups on the inner wall face. When a high pressure is applied, conventional ion exchange resins and ion exchange fibers are densely filled to increase the resistance to liq. flow and the shapes are eventually broken. The ion exchange hollow molded item of the present invention has excellent pressure resistance and high freedom of the shape in comparison with the conventional ion exchange products. When this tube is bent to form a coil shape, etc., an effective area can be sufficiently ensured. It can be effectively used in the field of instrumental analysis such as ionic liq. chromatography where especially high separation efficiency is required.

Abstract: PURPOSE:To obtain a sheet-like material which has excellent performance for removing fine particles and a long removing life and can refine chemical products, water, etc. by mixing and dispersing ion exchange fiber floc bodies and glass fibers and forming the sheet-like material. CONSTITUTION:This sheet-like material made of the ion exchange fibers for highly refining liquid and gases of chemical products, water, air, etc., consists of the mixed dispersion composed of the ion exchange fibers and glass fibers. The ion exchange fibers are formed by reinforcing the sea components consisting of polystyrene fibers contg. the exchange group having ion exchangeability, etc., with the island component such as polyalpha-olefin. Such ion exchange fibers are partially branched or divided to the floc bodies and thereafter the fibers are mixed with the glass fibers and the sheet is formed of such mixture. The resulted sheet-like material has small filtration resistance and the long filter life and is also effective for removing ultrafine particles.
