本文介绍了在一些上一代Ziegler-Natta催化剂体系存在下制备的聚丙烯样品的高分辨率150 MHz 13 C NMR表征的主要结果。特别是聚合物的构型分析，从五行水平（通常由常规光谱提供）扩展到非五行水平。这被证明对立体特异性起源的机制研究是有益的
This paper presents the main results of a high-resolution 150 MHz 13 C NMR characterization of polypropene samples prepared in the presence of a number of last-generation Ziegler-Natta catalyst systems. The configurational analysis of the polymers, in particular, was expanded from the pentad level (normally afforded by routine spectra) to the nonad level. This proved to be beneficial in mechanistic studies on the origin of the stereospecificity
