【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F₄₀试样,含氯量高达700ppm。更多还原

【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 than1 ppm and no chain transfer reaction was taken place while sample of F₄₀ whichhave 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.更多还原
