紫外吸收光谱在研究阴离子聚合活性种中是一种重要的研究工具,共振稳定的碳阴离子在近紫外区域能显示出特征吸收带,其位置往往与活性种的构型有直接的关系,而活性种的结构则影响到所得聚合产物的微观结构。众所周知,在丁二烯阴离子聚合中加入具有配位络
UV absorption spectroscopy is an important research tool in the study of anionic polymerization active species. The resonance stable carbon anions show characteristic absorption bands in the near UV region, and their positions are often directly related to the configuration of the active species. The activity The structure of the species affects the microstructure of the resulting polymer product. It is well-known that addition to butadiene anionic polymerization has a coordination network
