Ziegler-Natta catalysts are the workhorses of polyolefin production. However, although they have been used and intensively studied for half a century, there is still no comprehensive picture of their mechanistic operation. New techniques are needed to gain more insight in these catalysts. Solid-state NMR has reached a high level of sophistication over the last few decades and holds great promise for providing a deeper insight in Ziegler-Natta catalysis. This review outlines the possibilities for solid-state NMR to characterize the different components and interactions in Ziegler-Natta and metallocene catalysts. An overview is given of some of the expected mechanisms and the resulting polymer microstructure and other characteristics. In the second part of this review we present studies that have used solid-state NMR to investigate the composition of Ziegler-Natta and metallocene catalysts or the interactions between their components.
齐格勒-纳塔催化剂是聚烯烃生产的主力军。然而，尽管它们已经被使用和深入研究了半个世纪，但对于其作用机理仍没有全面的认识。需要新技术来更深入地了解这些催化剂。在过去几十年里，固态核磁共振技术已经达到了很高的水平，有望为深入了解齐格勒-纳塔催化作用提供更多信息。这篇综述概述了固态核磁共振技术用于表征齐格勒-纳塔催化剂和茂金属催化剂中不同组分及相互作用的可能性。文中还给出了一些预期机理以及由此产生的聚合物微观结构和其他特性的概述。在本综述的第二部分，我们介绍了利用固态核磁共振技术研究齐格勒-纳塔催化剂和茂金属催化剂的组成或其组分间相互作用的研究。
