This composition is prepared, for example, by electrolytic polymerization of an electrolytic solution containing at least the component (A) and aniline to form the complex of the component (A) and the component (B) on the electrode.

摘要： PURPOSE:To improve an abrasion resistance as a resin made piston and improve its productivity by forming the top part of a piston with the top of a metallic material made piston, and using heat-proof resin mixed with lubricant for a skirt part. CONSTITUTION:A resin made piston is constituted in such a way that a metallic material made piston top part 1 which is brought contact with a combustion chamber is integrated with a skirt part 2 constituted by heat-proof resin including lubricant. The heat proof resin used here is of at least one kind selected out of polyimide resin, condensed polycyclic multinuclear aromatic resin, polyamide-imide resin and phenolic resin. Fine particle shaped lubricant which is at least one kind selected out of graphite, molybdenum disulfide, organic molybdenum compound and fluoro resin is compounded within a range of 5 to 70weight% into this heat-proof resin. It is thus possible to apply the heat proof resin in a piston operated in such a condition as being very strict in both thermal and sliding view, and also improve heat resistance, abrasion resistance, and productivity.

摘要： PROBLEM TO BE SOLVED: To obtain the subject polymer capable of decreasing ion diffusion resistance within anodes by forming minute, thin pores in the highly dense conductive polymer. SOLUTION: This polymer is obtained by uniformly distributing minute, thin pores of a molecular size within pressured products of a conductive polymer material produced by chemical oxidation polymerization. For example, this polymer is obtained by mixing (A) a conductive polymer (e.g. polyaniline, polythiophen, etc.) obtained by chemical oxidation polymerization with a solvent (e.g. acetone, etc.) in which 1-30 wt.%, based on the component A, of a low molecular weight compound (e.g. lithium perchlorate, lithium tetrafluoroborate, etc.) is(are) dissolved, and pressing, without using any solvent, a mixture in which the low molecular weight compound is homogenously dispersed by evapolating the solvent only. Thus, the reaction diffusion resistance affecting the internal resistance of electrodes is decreased, resulting in occurrence of ideal charge-discharge reactions.
