【摘要】 <正> 应用等离子体聚合方法可以制备用化学方法难以得到的具有优异性能的聚合物,因此近年来引起国内外学者的重视,并对其聚合机理进行了探讨。但由于等离子体聚合反应的复杂性,至今尚未提出统一的反应机理。其争论的主要问题集中于反应活性中心是自由基还是离子,聚合反应是在气相还是在表面进行。对等离子体聚合过程中的气体产物分析与鉴定,将能对上述问题提供重要的依据。本文报导用色谱(GC),色谱-质谱联用(GC-MS)和顺磁共振(ESR)等方法分离和鉴定更多还原

【Abstract】 The paper reports the separation and identification of gaseous condensate from plasma polymerization of chlorotrifluoroethylene by means of GC, GC-MS and ESR. The GC-MS results of the conden sate on silica gel, SE-30 and Prorapak-Q columns have indicated that the conden sate consisted of 30 compounds. We have observed ESR signal with a hyperfine structure of 21 splitted lines from gaseous condensate of chlorotrifluoroethylene plasma polymerization. According to the GC-MS and ESR data, the reaction mechanism was deduced for plasma polymerization of chlorotrifluoroethylene.更多还原
