Abstract: PURPOSE:To easily form a tough conductive film having high conductivity on a substrate by wetting the insulating substrate surface with an electrolyte to carry out electrolytic polymerization and electrolytically polymerizing an aromatic compd. with the formed conductive polymer film of a tree shape, etc., as an anode. CONSTITUTION:A gold wire 2 is brought into contact with a part of the surface of the insulating substrate 1 as a working electrode, the surface, of the substrate 1 is wetted with the electrolyte 4 contg. a monomer to be electrolytically polymerized, and a part of the lower part is dipped in the electrolyte 4. A voltage is impressed between the gold wire 2 and a nickel plate 3 as a counter electrode in the electrolyte 4, and electrolytic polymerization is carried out. In this case, the potential gradient on the substrate 1 surface in the electrolyte film is controlled to >=1V/cm or preferably to about 5-100V/cm. As a result, a tree-shaped or reticular conductive polymer film is formed on the substrate 1 surface. An aromatic compd. is then electrolytically polymerized with the polymer film as an anode. Pyrrole, thiophene, benzene and their derivatives are appropriately used as the aromatic compd. By this method, a tough conductor film having excellent adhesion and high conductivity is formed on the substrate 1, and the insulating substrate surface is made conductive.

Abstract: PURPOSE:To obtain a cleaning agent compsn. with good foaming properties, reduced sliminess after rinsing and reduced irritativeness to skins by compounding a cationic surfactant with a specified polyethyleneimine polymer. CONSTITUTION:A copolymer (A) with repeating units of formulas I and II (wherein R is H, CH3 or C2H5; R is a 4-15C alkyl, aryl or aralkyl) in a wt. ratio of formula I to formula II of 9/1 to 1/9 (polyethyleneimine polymer) and a cationic surfactant (B) (e.g. octadecyltrimethylammonium chloride) are compounded. Even though the cationic surfactant has not only cleaning power but also bactericidal and bacteriostatic actions and is used for a skin cleaning agent for sterilization such as a cationic soap, there exist defects such as poor foaming, coarse foam and remaining of unpleasant sliminess after rinsing. It is possible by the abovedescribed combination to obtain a cleaning agent compsn. with good foaming reduction in unpleasant sliminess after rinsing and reduced irritativeness to the skins.

Abstract: PURPOSE:To obtain a cleaning agent compsn. being mild to the skins and having fine and good foam quality, excellent cleaning power and excellent touch after cleaning by compounding an amphoteric surfactant with a specified polyethyleneimine polymer. CONSTITUTION:A copolymer (A) with repeating units of formulas I and II (wherein R is H, CH3 or C2H5; R is a 4-15C alkyl, aryl or aralkyl) in a wt. ratio of formula I to formula II of 9/1 to 1/9 (polyethyleneimine polymer) and an amphoteric surfactant (B) (e.g. laurylaminopropionic acid) are compounded. Even though the amphoteric surfactant is mild to the skin and has good foaming properties, it exhibits coarse foam quality and insufficient cleaning power to sebum and oils. It is possible by the abovedescribed combination to obtain a cleaning agent compsn. with fine foam, high cleaning power and good touch after cleaning.

Abstract: PURPOSE:To obtain a cleaning agent compsn. with excellent foaming and cleaning power, good massaging effect and reduced irritativeness to skins and hairs by compounding a specified polyethyleneimine polymer with a water-soluble polymer compd. CONSTITUTION:A copolymer (A) with repeating units of formulas I and II (wherein R is H, CH3 or C2H5; R is a 4-15C alkyl, aryl or aralkyl) in a wt. ratio of formula I to formula II of 9/1 to 1/9 (polyethyleneimine polymer) and a water-soluble polymer compd. (B) (e.g. xanthan gum or polyethylene glycol) are compounded. When the polyethyleneimine polymer, which is one of nonionic surfactants, is used as a main cleaning base, the compsn. has excellent foaming power and reduced irritativeness, but there remain problems to be improved such as undesirable massaging effect caused by the occurrence of scrooping when cleaning is performed by using it as a cleaning agent for skins. It is possible by the abovedescribed combination to obtain a cleaning agent compsn. with excellent foaming and cleaning power, good massaging effect and reduced irritativeness to skins and hairs.

Abstract: PURPOSE:To improve high frequency characteristics and to reduce leakage current by introducing alcohol solution of oxidizing agent to the surface of deviative of a porous formed body, by bringing it into contact with water solution of pyrrole or pyrrole deviate and by forming a solid electrolyte through oxidation polymerization. CONSTITUTION:Oxidizing agent alcohol solution is introduced to the surface of deviative of a porous formed body; thereafter, it is brought into contact with water solution of pyrrole or pyrrole deviative and oxidation and polymerization are carried out; and then, a solid electrolytic layer which consists of highly conductive polypyrrole or dielectric thereof is formed on a surface of a dielectric inside a fine hole. Since oxidization agent is alcohol solution, it penetrates well inside the fine hole to cover a surface thereof. Since it is brought into contact with water solution of pyrrole or dielectric of pyrrole in the state, pyrrole or dielectric of pyrrole also penetrate well inside the fine hole and come into contact with oxidizing agent. Thereby, a solid electrolytic layer consisting of polymer of uniform and highly conductive polypyrrole or pyrrole deviative is formed on the surface of deviative inside the fine hole in a short time.
