在以前的工作中,我们曾应用色谱-质谱(GC-MS)及顺磁共振(ESR)等方法研究了四氟乙烯和三氟氯乙烯等离子体聚合过程中气体冷凝物的组成及结构,提出自由基引发聚合反应机理。本文用类似方法研究六氟丙烯(HFP)等离子体气体冷凝物的组成与结构和冷凝物的ESR信号及其从低温到高温的变化规律,证实了自由基的稳定性并提出气相聚合反应机理。
In previous work, we have studied the composition and structure of gas condensates during the polymerization of tetrafluoroethylene and chlorotrifluoroethylene using GC-MS and ESR methods. Radical polymerization mechanism. In this paper, the composition and structure of gas condensate of hexafluoropropylene (HFP) plasma and the ESR signal of condensate were studied in a similar way. The stability of free radical and the mechanism of gas phase polymerization were also discussed.
