  Transition metal complex, catalyst composition including the same and olefin polymer using catalyst composition

  摘要：

  提供一种新型的过渡金属配合物，其中单环戊二烯基配体引入了氨基基团进行配位，还提供了包括该配合物的催化剂组合物以及使用该催化剂组合物的烯烃聚合物。该过渡金属配合物具有五边形环结构，其中通过苯基桥连接的氨基基团在金属位点附近形成了稳定的键，因此，具有立体位阻的单体可以轻松接近过渡金属配合物。通过使用包括该过渡金属配合物的催化剂组合物，可以在具有大立体位阻的单体聚合中生产具有高分子量的线性低密度聚烯烃共聚物和密度为0.910 g/cc或更低的超低密度聚烯烃共聚物。此外，对于具有大立体位阻的烯烃单体的反应性能也非常优异。

  Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
