摘要:
This invention relates to a method for removing unreacted monomers and other volatile matters from a polymer solution composition produced from a mixture containing an aromatic vinyl monomer, utilizes two or more flash devolatilizing vessels, and effects the removal by adjusting the solid content of the polymer solution composition at the outlet of the devolitilizer before the last-stage devolitilizer to a level in excess of 97%, adding 0.5-4 parts by weight of a foaming agent to the total polymer solution composition, passing the polymer solution composition through the last-stage devolitilizer while maintaining the pressure of the polymer solution at 10 kg/cm2 or more by means of a pressure controller and the temperature in the range 190-260° C., introducing the polymer solution composition to a vapor-liquid separation vessel maintained at a vacuum of 20 Torr or less, and allowing the composition to foam.

摘要:
Provided is a sealing structure of a photoelectric conversion element in which the open side end section of the photoelectric conversion element can be surely and continuously sealed by a simple structure with high durability, and also the problem of insufficient sealing of the extraction electrode can be solved. A sealing structure 10 of a dye-sensitized solar cell as an example of the photoelectric conversion element is configured by a cylindrical dye-sensitized solar cell main body 12 and sealing sections 14a and 14b which respectively seal both ends of the dye-sensitized solar cell main body 12. Lid bodies 26a and 26b, each of which is formed of a conductive metal member, are respectively provided at both end sections of a transparent glass tube 16, so as to seal the dye-sensitized solar cell main body 12, and are also respectively electrically connected to a pair of electrode sections of the dye-sensitized solar cell main body 12, so as to be used as a pair of extraction electrodes.
