  Disclosed is an olefin polymerization catalyst comprising a transition metal selected from metals of Groups IIIA including the lanthanide series, IVA, VA, VIA, VIIA and VIII of the Periodic Table of the Elements, and ligands L¹ and L² bonded thereto, wherein a combination of L¹ and L² is (1) a combination of ligand L¹ which is a group containing at least one phosphorus-containing group and ligand L² which is a ligand having a σ-bond, or a ligand having a σ-bond and a bond selected from at least one π-bond and at least one lone electron pair donative bond; (2) a combination of ligand L¹ which is a 5-membered heterocyclic pentadentate ligand having one or more heteroatoms and ligand L² which is a ligand having a σ-bond, or a ligand having a σ-bond and a bond selected from at least one π-bond and at least one lone electron pair donative bond, provided that when the pentadentate ligand contains only one heteroatom, L² is a ligand having a σ-bond, or a ligand having a σ-bond and at least one lone electron pair donative bond; and (3) a combination of ligand L¹ which is a trispyrazolyl tridentate ligand and ligand L² which is an alkapolyenyl ligand, and wherein each L¹ contains an element of Group VB or Group VIB. The catalyst of the present invention has extremely high catalytic activity for an olefin polymerization reaction as compared to conventional olefin polymerization catalysts.

  本发明公开了一种烯烃聚合催化剂，该催化剂包含选自元素周期表中包括镧系在内的IIIA族、IVA族、VA族、VIA族、VIIA族和VIII族金属的过渡金属，以及与其结合的配体L¹和L²、其中 L¹ 和 L² 的组合是 (1) 配体 L¹ 是含有至少一个含磷基团的基团，配体 L² 是具有 σ 键的配体，或具有 σ 键和选自至少一个 π 键和至少一个孤电子对捐赠键的键的配体的组合；(2) 配体 L¹ 的组合，配体 L¹ 是具有一个或多个杂原子的五元杂环配体，配体 L² 是具有σ键的配体，或具有σ键和选自至少一个π键和至少一个孤电子对捐赠键的配体、条件是当五价配体只含有一个杂原子时，L² 是具有一个 σ 键的配体，或具有一个 σ 键和至少一个孤电子对捐赠键的配体；和 (3) 配体 L¹（三异吡唑三叉配体）和配体 L²（烷基多烯配体）的组合，其中每个 L¹ 包含一个 VB 族或 VIB 族元素。与传统的烯烃聚合催化剂相比，本发明的催化剂对烯烃聚合反应具有极高的催化活性。
