    摘要： An electrorheological fluid composition is composed of a dispersed phase of dielectric solid particles and a dispersion medium of an electrically insulating solution, wherein the solution is composed of 99-75% by weight of silicone oil and 1-25% by weight of an organic compound having at least one unsaturated bond. The composition generates a large shear stress even under an electric field of relatively low intensity, and the concurrent current density is small. The composition shows excellent performances also in terms of its withstanding dielectric breakdown strength under an electric field of high intensity and the fluidity and re-dispersibility in the absence of an electric field. In the meantime, the composition has high durability of the generated shear stress and the current density.

    摘要： The sulfonation of a polyaniline or a derivative thereof by the use of a sulfonating agent, characterized by dispersing the polyaniline or the derivative thereof in a reaction solvent thereby inhibiting the formation of lumps of grains due to substantial aggregation. Preferably, the solvent for the reaction is an organic solvent incapable of reacting with the sulfonating agent. The initial stirring power for the reaction of sulfonation is preferred to be not less than 0.03 kW/m3 and the polyaniline or the derivative thereof is preferred to have a water content of not more than 8 wt. %. Further, this invention is characterized by subjecting a polyaniline having introduced a sulfonic acid group therein or a derivative thereof to hydrolysis in a mixed solution of water with a hydrophilic organic solvent. The hydrophilic organic solvent is preferred to be an alcohol. The aqueous solution of the water-soluble conducting polyaniline obtained by the method of production mentioned above can be made to form a thin film by a simple technique such as spin coat, dip coat, or bar coat and utilized for various antistatic applications and non-linear optical materials.

    摘要： According to the present invention, electrorheological fluid is deaerated after it is sealed in a closed device which is operated by the electrorheological fluid. Thus, it is possible to control the operation of the closed device in accordance with an electric field. Additionally, the control of viscosity is not affected by repetitive operations of the closed device, thereby obtaining a closed device having a smooth operation and good repeatability. The deaeration is achieved under a predetermined reduced pressure, for example, of not more than 100 torr. In addition thereto, a suitable heating process is carried out as required.

    摘要： For example, a blended composition is produced first by letting a monomer composition, mainly composed of alkyl (meth)acrylate and including a compound having a plurality of polymeric groups within a molecule, contain microscopic particles, such as carbon black, having an average primary particle size in a range between 1 nm and 200 nm, and then the blended composition is polymerized. Consequently, it has become possible to produce inexpensive crosslinked elastomer having excellent physical properties, such as small creep (low creep) in compression set, tensile elongation set, etc., and excellent mechanical strength, such as tensile break strength and tensile break elongation, in a simple procedure omitting the post-crosslinking step at a high-level productivity while saving energy and time spent in the kneading step.
