Zusammenfassung:The invention relates to a method for producing polysulfane silanes of formula I (R1) 3-mR2mSi-R3-Sx-R3-SiR2m (R1) 3-m I by reacting at least one silane of formula II (R1) 3-mR2mSi-R3-Hal II with M (SH) y and/or MzS and sulfur in the presence of a phase transfer catalyst of formula, wherein at least one carrier vapor distillation and/or ozone treatment is carried out during or after the reaction. 本发明涉及一种用于制备式I的聚硫烷硅烷的方法(R1)3-mR2mSi-R3-Sx-R3-SiR2m(R1)3-m I做法是在式的相转移催化剂的存在下使至少一种式II的硅烷(R1)3-mR2mSi-R3-Hal II与M(SH)y和/或MzS和硫反应，其中在反应期间或之后进行至少一次载体蒸气蒸馏和/或臭氧处理。
