| 摘 要： | 四氟乙烯和全氟4-甲基-3,6-二氧杂-△~7辛基磺酰氟在溶剂氟里昂-113(F-113)中进行自由基引发聚合反应时,共聚物(T-O)是否有链转移,可以通过测定所得共聚物中的含氯量来得以证实。我们首次应用质子X萤光分析法(PIXE)进行分析。结果表明,共聚物中含氯量小于1ppm,F-113溶剂并未发生链转移。同时,我们测定了已证明有F-113参与链转移反应的F_(40)试样,含氯量高达700ppm。

| Abstract: | PIXE method was used the first time in the analysis of copolymers.
The results showed that the chlorine content in the copolymer is less than
1 ppm and no chain transfer reaction was taken place while sample of F_(40) which
have already been confirmed to have chain transfer reaction in F-113 was ana-
lysed and the chlorine content was found to be as high as 700 ppm. |
