Using specific ether solvents, successful control of the direct reaction of sodium metal with elemental sulfur was attained. Especially, use of dimethoxyethane gave the best result. In this system, anhydrous sodium oligosulfide in which composition was corresponded to the feed ratio was obtained. Further, the reaction of the oligosulfide with 3-(triethoxysilyl)propyl chloride afforded corresponding silane coupling agent having oligosulfide structure quantitatively. To reveal the distribution of sulfur chain of oligosulfide, the oligosulfide was reacted with alkylation agent such as methyl iodide, butyl bromide, and benzyl chloride as the model reaction. The resulting dialkyloligosulfides were isolated to determine the structure and the distribution of sulfur chains by various spectroscopic analyses. The relationship between the sulfur chain distribution and the physical properties of the rubber was discussed. Further, in comparison of the silane coupling agent obtained in this study with that commercially available, the former is superior to the latter as the additive for the tire thread because thermal crosslinking was suppressed.

使用特定的醚溶剂，成功控制了金属与元素硫的直接反应。尤其是，使用二甲乙烷可以带来最佳效果。在该系统中，获得了与饲料比相对应的无水钠硫化钠。此外，寡聚硫化物与3-（三氧基二烯基）的丙二酰氯化物的反应提供了相应的硅烷偶联剂，具有寡硫化物结构。为了揭示寡硫化物硫链的分布，将寡硫化物与烷基化剂（如甲基碘化物，丁基溴化物和氯化苯甲酰氯化物）反应为模型反应。分离产生的二烷基硫硫化物，以通过各种光谱分析来确定硫链的结构和分布。讨论了硫链分布与橡胶的物理特性之间的关系。此外，与该研究中获得的硅烷耦合剂与市售的硅烷耦合剂进行了比较，前者优于后者作为轮胎螺纹的添加剂，因为热交联被抑制了。
