    • In an electrolytic treatment of alkali halide for the manufacture of alkali hydroxide, a three-chamber type reaction vessel assembly is used so as to provide an anodic chamber, an intermediate chamber and a cathodic chamber arranged in succession one after another and mutually separated by means of anodic (i.e., cationic selective) ion exchange membranes. From the intermediate chamber, low concentration caustic alkali solution is obtained, while from the cathodic chamber, high concentration caustic alkali solution is obtained. In this electrolytic process, the system is operated with the cathodic chamber supplied with no water or aqueous content. The high concentration caustic alkali solution is made from water and alkali metal ions conveyed from the intermediate chamber to the cathodic chamber and exclusively and osmotically passed through the anodic ion exchange membrane. The polymers or copolymers of the anodic ion exhange membrane include sulfonic acid, carboxylic acid and/or phenolic radicals. As the method for the introduction of these radicals, formation of corresponding copolymers may be utilized in the most recommended way. As an example, the membrane may comprise a fluorinated polymer having a cyclic ring structure unit and pendant type sulfonic acid radicals.
    • 在用于制造碱金属氢氧化物的碱金属卤化物的电解处理中,使用三室式反应容器组件,以便提供一个接一个地连续排列并相互分离的阳极室,中间室和阴极室 的阳极(即阳离子选择性)离子交换膜。 从中间室获得低浓度苛性碱溶液,而从阴极室获得高浓度苛性碱溶液。 在这种电解过程中,系统在没有水或含水量的阴极室运行。 高浓度苛性碱溶液由从中间室输送到阴极室的水和碱金属离子制成,并且渗透通过阳极离子交换膜。 阳离子离子膜的聚合物或共聚物包括磺酸,羧酸和/或酚基。 作为引入这些基团的方法,可以以最推荐的方式使用相应的共聚物的形成。 作为示例,膜可以包含具有环状结构单元和侧链型磺酸基团的氟化聚合物。

    • An electrooptical solid element comprises a formed resin composition comprising a low molecular polar substance having a Kerr type electrooptical effect, and an organic polymer substance compatible with the low molecular polar substance. The formed resin composition is prepared by a method such as melt mixing on rollers, or dissolution in a common solvent followed by evaporation of the solvent. This formed resin composition is prepared in various shapes such as a polygon, a film, a prism and a polygonal pole. At least a pair of electrodes are provided on the surfaces of the formed resin composition, and further at least one of the electrodes may can be made of a transparent material.
