离聚体的结构表征:Ⅱ.含氟离聚体的FT—IR研究
-
摘要: 本文报导了以甲基丙烯酸氟醇酯-丙烯酸共聚物为基础的羧酸型钙、钠离聚体在不同温度及时间下的FT-IR图谱的变化规律。探讨了在离聚体聚集态中钙、钠离子的局部配位形式及结构。Abstract: In this paper, the structures of fluorine--containing Ca--and Na--ionomers werecharacterized by Fourier--transform infrared spectrometry. We observed that theasymmetric stretching vibrating absorption of the carboxylate ion was divided intooverlapping pea
