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。
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 peaks at high temperature. The frequency, relative intensity and bandWidth of these IR bands depend upon the temperature, time and the nature of thecattions. The double at 1597/1587c^(-1) were assigned to be ionic multipletes and clus-ters respectively in the IR spectra of Calcium ionomer and the phenomena were ob-served in the IR spectra of Sodium ionomer. The structures of ionomers were a largeerosslinked network linked with ionic microdomains.
