通过茂金属与苯氧亚胺锆配合物的结合，合成了三核配合物。经甲基铝氧烷（MAO）活化后，这些催化剂对乙烯具有中等和较好的催化活性。由于不同催化中心的存在，得到了具有宽或双峰分子量分布的聚乙烯。(C)2007 Elsevier B.V.保留所有权利。
Trinuclear complexes were synthesized by combination of metallocene and phenoxyimine zirconium complexes. After activation with methylalumoxane (MAO), these catalysts polymerize ethylene with moderate and good activities. Due to the presence of different catalytic centers, polyethylenes with broad or bimodal molecular weight distributions were obtained. (C) 2007 Elsevier B.V. All rights reserved.
