摘要： PURPOSE:To obtain a porous polymer particle having a large specific surface area because of its porous structure by bringing polymer particles containing a monomer and a pore-forming agent into contact with supercritical carbon dioxide. CONSTITUTION:The purpose particles are obtained by bringing polymer particles containing a monomer and a pore-forming agent into contact with supercritical carbon dioxide to remove the residual monomer and the pore-forming agent from the polymer particles. This process is desirable especially when the polymer particles are those prepared by suspension-polymerizing a mixture of divinylbenzene with glycidyl methacrylate in an aqueous medium by using 4- methyl-2-pentanol as the pore-forming agent and having excellent mechanical strengths and adsorptivity. According to the production process of the above porous polymer particles, unreacted monomer and a pore-forming agent can be effectively extracted and separated from the polymer particles by using supercritical carbon dioxide and therefore a porous polymer applicable to many fields can be produced.

摘要： PURPOSE:To obtain a toner with an excellent ambient stability by polymerizing a polymeric vinyl monomer to compose a binder resin and a monomer mixture including a colorant in a mixture dispersion medium made by mixing a specific amount of water and methanol. CONSTITUTION:A polymeric vinyl monomer to compose a binder resin and a monomer mixture including at least a colorant are polymerized in a mixture dispersion medium in which a hard water-soluble inorganic substance powder is used as a dispersant, and 20 to 80wt.% of water and 80 to 20wt.% of methanol are mixed. As a result, a minute particle toner with uniform particle diameter of the mean particle diameter 10mum or smaller suitable for forming a high resolution image can be manufactured economically. Furthermore, the particle diameter can be controlled by only changing the mixing ratio of the water and the methanol, and no special dispersant is necessary to use. Consequently, the ambient stability of the toner obtained in such a way is excellent.

摘要： PURPOSE:To obtain the titled polymer particles excellent in adsorbability by subjecting a mixed monomer consisting of 35-100wt.% divinylbenzene and 0-65wt.% glycidyl methacrylate to suspension polymerization in an aqueous medium while using 5-12C monovalent alcohol as a precipitant. CONSTITUTION:A mixed monomer consisting of 35-100wt.% divinylbenzene and 0-65wt.% glycidyl methacrylate is subjected to suspension polymerization in an aqueous medium by using monovalent alcohol wherein the atomic number of carbon is 5-12 and the solubility for water is 7 and below (e.g. 3,5,5- trimethylhexanol or the like) as a precipitant. Porous polymer particles are obtained for example by firstly washing the produced polymer with water and then washing it with methanol and furthermore subjecting it to Soxhlet extraction until it shows constant weight. The polymer particles can be preferably used as an adsorbent of bilirubin. Further as the amount of the precipitant, 80-150pts.wt. is used especially preferably for 100pts.wt. mixed monomer.

摘要： PURPOSE:To obtain an immobilizing carrier, consisting of DVB polymer particles having a macroporous structure and capable of readily and efficiently carrying out immobilization of enzymes, etc., for reaction of a water-insoluble substrate. CONSTITUTION:50-120pts.wt. precipitating agent, preferably 4-methyl-2-pentanol is added to 100pts.wt. high-purity DVB (divinylbenzene) or industrial DVB monomer consisting of a blend of ethylvinylbenzene with other various kinds of saturated compounds and suspension polymerization is carried out in water. The resultant polymer particles are initially washed with water, then methanol and further extracted with acetone until a constant weight is attained in a Soxhlet extractor. The precipitating agent and unreacted monomer remaining in the particles are removed to afford the aimed macroporous DVB polymer particles having 0.25-1.65cc/g pore volume (measured by a mercury porosimter) and a pore diameter within the range of 140-2,000Angstrom . The above-mentioned particles are directly used as a carrier for immobilization without requiring activation treatment.

摘要： PURPOSE:To readily obtain the subject real round particles having a remarkably narrow particle size distribution without using a special dispersant by using a specified hydrophilic solvent as a dispersion solvent in dispersion polymerization of benzyl methacrylate monomer. CONSTITUTION:In polymerization of benzyl methacrylate (monomer) in a hydrophilic solvent containing a polymer dispersant dissolved therein, a hydrophilic mixture solvent composed of 60-100wt.% methyl alcohol and 40-0wt.% N,N'-dimethylformamide is used to obtain the objective particles. In addition, the above-mentioned polymerization is preferably carried out by using a polymerization initiator in an amount of 0.2-5wt.%, based on the monomer, at 45-110 deg.C under stirring of 100-500rpm of agitation. As the polymer dispersant, polyvinyl pyrrolidone or PVA is preferable.

摘要： PURPOSE:To improve flowability, etc., by dispersing and dissolving a raw material mixture which contains a coloring agent, magnetic particles, binding material for pressure fixation, and capsule wall forming resin in an organic solvent, dispersing the mixed solution in dispersion stabilizing liquid and removing the solvent, and further extracting alcohol and drying it. CONSTITUTION:The raw material mixture of either of a coloring agent such as carbon black and coloring pigment and magnetic particles, higher fatty acid or its amide, natural or synthetic wax, and binding material for pressure fixation such as natural or synthetic resin is dispersed and dissolved in a solvent of toluene and this mixed solution is dispersed in a solution containing a dispersion stabilizer such as gum arabic. Then, the toluene is removed by the azeotrope of the solvent of toluene, etc., and water to obtain remaining toner particles by filtration. The toner particles are dispersed in lower alcohol again and alcohol in the toner particles is extracted, filtered, and dried under reduced pressure. Thus, the toner has a uniform particle size distribution, a nearly spherical shape, and superior flowability and resolving power, etc., and neither causes mutual cohesion nor leave an offset at a roll, etc., and fixation is performed under low pressure.
