  The conductive polymer of the present invention is prepared by means of oxidation polymerization. On the matrix of the conductive polymer, at least one organic sulfonate formed by an anion of an organic sulfonic acid and a cation of other than transition metals is coated. Alternatively, in the matrix of the conductive polymer, at least one organic sulfonate formed by an anion of an organic sulfonic acid and a cation of other than transition metals is included. The conductive polymer of the present invention is excellent in the conductivity, heat resistance and moisture resistance. By using it as a solid electrolyte, a reliable solid electrolytic capacitor can be prepared which is unlikely to decrease the properties when being kept in a hot and humid condition.

  本发明的导电聚合物是通过氧化聚合制备的。在导电聚合物的基质上，至少涂覆了一种由有机磺酸阴离子和过渡金属以外的阳离子形成的有机磺酸盐。或者，在导电聚合物的基质中，至少包含了一种由有机磺酸阴离子和过渡金属以外的阳离子形成的有机磺酸盐。本发明的导电聚合物具有优异的导电性、耐热性和耐潮湿性。将其用作固体电解质，可以制备出可靠的固态电解电容器，在热湿条件下使用时不太可能降低其性能。

  Disclosed is a polycondensation product comprising A) an aromatic or heteroaromatic compound containing 5 to 10 C atoms or heteroatoms, said compound being provided with an average of 1 to 300 oxyethylene groups and/or oxypropylene groups per molecule which are linked to the aromatic or heteroaromatic compound via an O atom or N atom, and optionally B) an aromatic compound selected among the group comprising phenols, phenol ether, naphthols, naphthol ether, anilines, furfuryl alcohols, and/or an aminoplast former selected among the group comprising melamine (derivatives), urea (derivatives), and carboxylic acid amides, and C) an aldehyde selected among the group comprising formaldehyde, glyoxylic acid, and benzaldehyde or mixtures thereof, the benzaldehyde optionally containing acid groups in the form of COOM a , SO 3 M a , and PO 3 M a , wherein M=H, akali metal or alkaline earth metal, ammonium, or organic amine radicals and a=½, 1, or 2. Surprisingly, the inventive polycondensation product causes very good liquefaction of hydraulic binding agents, e.g. cement, resulting in substantially improved liquefaction of the construction material at a lower dose while pourability can be maintained over a longer period of time as opposed to naphthalene sulfonates or melamine sulfonates.

  本发明涉及一种聚合物缩合产物，包括A）含有5至10个碳原子或杂原子的芳香或杂芳香化合物，该化合物每个分子平均含有1至300个氧乙烯基团和/或氧丙烯基团，这些基团通过O原子或N原子与芳香或杂芳香化合物连接，以及可选的B）从苯酚、苯醚、萘酚、萘醚、苯胺、呋喃基醇和/或从三聚氰胺（衍生物）、脲（衍生物）和羧酸酰胺中选择的氨基塑料成形剂中选择的芳香化合物，和C）从甲醛、乙酰甲酸和苯甲醛或其混合物中选择的醛，其中苯甲醛可选地含有COOMa、SO3Ma和PO3Ma形式的酸基团，其中M = H、碱金属或碱土金属、铵或有机胺基团，且a = ½、1或2。令人惊讶的是，本发明的聚合物缩合产物可以非常好地液化水泥等水泥基材料，从而在较低剂量下显着改善了建筑材料的液化性能，同时可以保持易倒性，而不像萘磺酸盐或三聚氰胺磺酸盐那样在更长时间内保持易倒性。

  Rinsable dyes with improved fugitivity are formulated by attaching dyestuff compounds with amine-capped sulfonic solubilizing groups to commercially available ethoxylated aniline, so that the surfactant effect of the ethoxylated aniline counteracts the substantivity of the dyestuff compound, while the neutralization of the sulfonic solubilizing groups reduces substantivity.

  可洗的染料具有改进的耐洗性，通过将染料化合物与胺端基磺酸溶解基团连接到商业可得的乙氧基苯胺上来配制，使得乙氧基苯胺的表面活性剂效应抵消了染料化合物的亲和性，而磺酸溶解基团的中和则降低了亲和性。
