  摘要：

  通过异硫酸钠、丙烷磺内酯和丁烷磺内酯与分别由 10、11 和 12 个碳原子组成的正常主脂肪酸制备了一系列磺烷基烷酸钠（RCOO(CH2)jSO3Na）。研究了酯基位置对这些表面活性剂的克拉夫特点、临界胶束浓度（CMC）、表面滞留以及其他表面和胶体特性的影响。在碳原子数一定的情况下，将酯基从离子头移至碳氢链的更中心位置可提高 CMC 值和钙离子稳定性，并降低乳液稳定性和水解稳定性。不过，润湿时间受这些化合物中酯基位置的影响不大。当酯基移到更中心的位置时，这些表面活性剂的克拉夫特点会降低。

  Bei Füllstoff enthaltenden Kunststoff-Formmassen wird eine sehr gute Verträglichkeit zwischen dem hydrophilen Füllstoff und der hydrophoben Polymermatrix erreicht, wenn als Haftvermittler Alkalisalze von Alkyl- bzw. Alkylensulfonsäuren oder Alkylsulfaten und ihren Derivaten sowie die diesen Salzen zugrundeliegenden Säuren verwendet werden. Dabei werden das Fließverhalten der Formmassen und die mechanischen Eigenschaften der daraus hergestellten Kunststoffgegenstände verbessert.

  在含有填料的塑料模塑料中，如果使用烷基或亚烷基磺酸或烷基硫酸盐的碱盐及其衍生物以及这些盐所基于的酸作为附着力促进剂，亲水性填料和疏水性聚合物基体之间就会产生很好的相容性。这样就能改善模塑化合物的流动性和用其生产的塑料制品的机械性能。

  To provide a surfactant which is obtainable by using substantially no alkali metal, has excellent readhesion prevention ability of finely-pulverized particles at the time of cleaning, and is capable of quite efficient and advanced cleaning. In the present invention, a surfactant which comprises a neutralized salt (AB1) and/or neutralized salt (AB2) is used. Neutralized salt (AB1): a neutralized salt (AB1) which comprises an acidic compound (A1) containing at least each one of an acid group (X1) of an acid having the difference of heat of formation in an acid dissociation reaction (Q1) of 3 to 200 kcal/mol and a hydrophobic group (Y) containing 1 to 36 carbon atoms, and a nitrogen-containing basic compound (B) having the difference of heat of formation in a proton addition reaction of 10 to 152 kcal/mol, wherein (X1) is at least one species selected from a sulfonic acid group, and the like. Neutralized salt (AB2): a neutralized salt (AB2) which comprises a polymer (A2) having at least one acid group (X2) within the molecule, and the nitrogen-containing basic compound (B) having the difference of heat of formation in a proton addition reaction of 10 to 152 kcal/mol.

  An adhesive composition including resin and electro-conductive material, wherein the electro-conductive material is one or more salts from sodium salt, potassium salt, and calcium salt of fluorosulfonic acid having 5 or more carbon atoms shown by the general formula (1): (R 1 —X—Y—SO 3 − ) n M n+ (1), wherein, R 1 represents a monovalent hydrocarbon group having 1-30 carbon atoms and optionally substituted by a heteroatom or optionally interposed by a heteroatom; X represents any of a single bond, ether group, ester group, and amide group; Y represents a linear or branched alkylene group having 2-4 carbon atoms, containing 1-6 fluorine atoms, and optionally containing a carbonyl group; M n+ represents any of a sodium ion, potassium ion, and calcium ion. This can form a living body contact layer for a bio-electrode with electric conductivity, biocompatibility, and light weight, which can be manufactured at low cost and without electric conductivity large lowering even when wetted with water or dried.
