用傅里叶变换红外透射光谱研究了溶液聚合的四种模型嵌段共聚物——聚氨酯-氨酯、聚脲-氨酯、聚氨酯-脲、聚脲-脲——在硬段微区和相界面区氢键的情况,并与衰减全射谱在分析这些模型嵌段共聚物时的情况进行了对比。
Four kinds of model block copolymers - polyurethane - urethane, polyurea - urethane, polyurethane - urea, and polyurea - urea - were investigated by Fourier transform infrared transmission spectroscopy in hard segment and phase Hydrogen bond in the interface region, and compared with the case of attenuated full spectrum in analyzing these model block copolymers.
