用ESR分析了三氟氯乙烯(CTFE)和六氟丙烯(HFP)等离子体聚合的气体冷凝物和固体膜,其气体冷凝膜有70条超精细裂分线.并研究了它的ESR信号随温度的变化,把气体冷凝物和固体膜分别在室温中暴露在空气中三个月,十六个月或十五个月,ESR信号依然存在,这表明有十分稳定的游离基存在.

The gaseous condensate of poly(chlorotrifluoroethylene) [9002-83-9] and poly(hexafluoropropylene) [25120-07-4] prepared by plasma polymerisation showed ~70 hyperfine splitting lines at 30? The no. of splitting lines reduced to 12 when the temperature increased to >90? The ESR signals remained even after exposure to air at ambient temperature for 3, 6, or 15 mo, indicating the stability of free radicals in these films.
