研究了四氟乙烯齐聚反应及其产物的应用.从四氟乙烯起始用氟离子引发获得得率为78%的四氟乙烯齐聚体,并确定四、五聚体的结构分别为Ⅰ和Ⅱ.五聚体的苯磺酸钠衍生物(Ⅵ)可成功地应用于无氰电镀工艺中铜镀件的电解去油污.

We have studied tho oligomerization of tetrafluoroethylone and its application, Oligomerization of tetrafluoroethylene catalyzed by fluoride ion produced an easily separable mixture of oligomers in 78% yield.The structures of the tetramers and pentamer were confirmed as Ⅰ and Ⅱ respectively.The sulphonate derivative of the pentamer (Ⅵ) has been used satisfactorily as a degreasing agent for non-cyanide electroplating on copper.
