It is intended to provide a conductive polymer dispersion which has an excellent conductivity and is capable of providing a material with high transparency; and a process for producing the same. The process for producing a conductive polymer dispersion comprises a stirring step in which a mixed liquid containing a conductive polymer having a weight-average molecular weight of from 20,000 to 1,000,000 and a solvent is stirred at a shearing rate of 10,000 sor higher using a stirring machine thereby obtaining a conductive polymer dispersion in which the conductive polymer is dispersed in the solvent.

A method and a device for directly molding a glazing gasket by extruding a molding material from a molding die to a peripheral edge part of a double-glazing panel in which a space layer is formed between two adjacent glass sheets with a spacer interposed in between. The molding die is configured of a front die and a rear die, which are independent of each other. The front die is allowed to adhere closely to at least the front surface of the double-glazing panel, and the rear die is allowed to adhere closely to at least the rear surface of the double-glazing panel, thereby molding the glazing gasket.

A water pump is connected to a mixer so as to blast high pressure water at a high speed in the mixer. The air and powder are supplied to the blast flow of the high pressure water through an air supply pipe and a powder supply pipe respectively so that a mixture flow composed of the gas, the droplet-like fluid, and powder is formed. The mixture flow is blasted from a nozzle at a high speed so as to be sprayed onto a surface to be treated. Thus, impact actions held by the powder and the droplet-like fluid as cleansing/scraping media are given to the surface to be treated. Thus, a cleansing/scraping operation is achieved. Then, if the fluid, gas or the like supplied to the mixer is heated, the cleansing/scraping operation can be further accelerated.
