    • A method for easily producing high-purity polydimethylsilane or polydiphenylsilane, where by-products such as alkali metal salt and alkaline earth metal salt can be efficiently removed, is provided. Dimethyldichlorosilane or diphenyldichlorosilane is reacted with an alkali metal such as metal sodium and metal magnesium and/or an alkaline earth metal in an organic solvent such as toluene to obtain crude polydimethylsilane or crude polydiphenylsilane, methanol having dissolved therein an ether ester-type nonionic surfactant or a surfactant such as alkylbenzenesulfonate is added to the crude polydimethylsilane or the crude polydiphenylsilane to deactivate the remaining alkali metal and alkaline earth metal, and the crude polydimethylsilane or the crude polydiphenylsilane is washed with water in the presence of a surfactant to efficiently remove an alkali metal salt, an alkaline earth metal salt and the like, whereby high-purity polydimethylsilane or polydiphenylsilane is obtained.
    • 提供容易生产高纯度聚二甲基硅烷或聚二苯基硅烷的方法,其中可以有效地除去碱金属盐和碱土金属盐等副产物。 二甲基二氯硅烷或二苯基二氯硅烷与有机溶剂如甲苯中的金属钠和金属镁和/或碱土金属的碱金属反应,得到粗的聚二甲基硅烷或粗的聚二苯基硅烷,其中溶解有醚酯型非离子表面活性剂的甲醇或 将烷基苯磺酸盐等表面活性剂加入到粗聚二甲基硅烷或粗聚二苯基硅烷中,使剩余的碱金属和碱土金属失活,粗面聚二甲基硅烷或粗聚二苯基硅烷在表面活性剂存在下用水洗涤,有效地除去碱金属 盐,碱土金属盐等,得到高纯度聚二甲基硅烷或聚二苯基硅烷。
