A catalyst system useful for polymerizing olefins is disclosed. The catalyst system comprises an activator and a Group 4 metal complex. The complex incorporates a dianionic, tridentate heterocyclic-8-anilinoquinoline ligand. In one aspect, a supported catalyst system is prepared by first combining a boron compound having Lewis acidity with excess alumoxane to produce an activator mixture, followed by combining the activator mixture with a support and the dianionic, tridentate Group 4 metal complex. The Group 4 metal complexes are easy to synthesize, support, and activate, and they enable facile production of high-molecular-weight polyolefins.
本文披露了一种用于聚合烯烃的催化剂系统。该催化剂系统包括一个活化剂和一个第四族金属配合物。该配合物包含一个二阴离子、三齿杂环-8-苯胺喹啉配体。在一个方面,通过首先将具有路易斯酸性的硼化合物与过量的氧化铝烷混合以产生活化剂混合物,然后将活化剂混合物与支撑物和二阴离子、三齿第四族金属配合物相结合来制备支撑催化剂系统。第四族金属配合物易于合成、支撑和活化,它们能够轻松地生产高分子量聚烯烃。
