Stereoselective polymerization of 1-alkenes was discovered 50 years ago. However, a detailed knowledge of the traditional and industrially used Ziegler-Natta catalytic systems is still missing. Recently, well-defined homogeneous and octahedral complexes that polymerize propene to polypropylenes with microstructures extremely similar to those of polymers produced with the traditional catalysts were discovered. These catalysts offer the exciting opportunity to achieve insights into the mechanism of stereocontrol operative with the traditional catalytic systems.
1-烯烃的立体选择性聚合是在50年前被发现的。然而，对于传统的、工业上使用的齐格勒-纳塔催化体系，仍缺乏详细的了解。最近，发现了一些结构明确的均相八面体配合物，它们能将丙烯聚合成微观结构与传统催化剂生产的聚合物极为相似的聚丙烯。这些催化剂为深入了解传统催化体系中立体控制的作用机制提供了令人兴奋的契机。
