    摘要: Encapsulated medicaments are prepared by dissolving a wall material for capsules in at least one organic solvent poorly miscible with water which has a boiling point of less than 100.degree.C., a vapor pressure higher than that of water and a dielectric constant of less than about 10, dissolving or dispersing in the resulting solution a medicament which is insoluble or slightly soluble in water, dispersing the resulting solution or dispersion to the form of fine drops in a liquid vehicle comprising an aqueous solution of a hydrophilic colloid or surface active agent, and then removing the organic solvent by evaporation.

    摘要: A novel molecular sieving particle containing adsorbent powders dispersed in matrix of micro-porous polymer gels is prepared by dispersing adsorbent powders into a polymeric material solution dissolved in a solvent, then emulsifying the thus prepared dispersion into a vehicle having a boiling point higher than that of the solvent and finally removing the solvent by evaporation. This molecular sieving particle has excellent molecular sieving effect as well as excellent adsorption capacity, and applicable in various applications.
