AB  - The introduction of well-defined, single-site organotransition metal olefin polymerization catalysts in the early 1980s highlighted the possibilities for controlling and dramatically improving the properties of commodity polymer products such as polyethylene and polypropylene. Group 4 metallocenes and half-sandwich titanium-amide complexes (constrained-geometry catalysts) have been at the forefront of these developments, and, as we approach the late 1990s, these catalysts are increasingly finding their way into commercial operations. However, it is generally acknowledged that no single class of catalyst will be capable of controlling all of the macromolecular parameters relevant to a wide and varied range of polyolefinic products. Over the past few years, an intense search has therefore developed, in both academic and industrial research laboratories, for new-generation catalysts. Some of the most significant recent developments have occurred with late transition metal systems. Particularly, the discovery of exceptionally active catalysts based on iron, a metal that had no previous track record of being applied in this way, has signposted the way for further technologically significant advances in the field. In this review, we highlight the key advances that have occurred in the discovery and development of non-Group 4 metallocene catalysts, amply demonstrating that there are significant signs of life beyond the Group 4 metallocenes. © Wiley-VCH Verlag GmbH, 1999.
