  Ethylene polymerization processes employing bis-imino pyridinyl transition metal components which exhibit C2, C2v or Cs symmetry. Catalyst components of the same or different symmetries may be employed to control polymerization characteristics and characteristics of the resulting polymer products such as polymer yield and polymer molecular weight. The transition metal catalyst component is characterized by the formula: wherein M is a Group 4-11 transition metal, n is an integer within the range of 1-3, Q is a halogen or a C 1 -C 2 alkyl group, and PY is a pyridinyl group which is coordinated with M through the nitrogen atom of the pyridinyl group. Further, with respect to formula (I), A is a methyl group, a phenyl group, or a substituted phenyl group and B, and B 2 are the same or different aromatic groups depending on the symmetry of the catalyst component. The catalyst component and an activating co-catalyst component are contacted with ethylene in a polymerization reaction zone which is free of hydrogen or contains hydrogen in an amount which is less than 5 mole % of the ethylene under polymerization conditions to produce a polymer product which can be a ethylene homopolymer or a copolymer of ethylene and C 3+ alpha olefin, specifically an ethylene-propylene copolymer.

  采用具有C2、C2v或Cs对称性的双亚胺吡啶基过渡金属组分的乙烯聚合过程。可以使用具有相同或不同对称性的催化剂组分来控制聚合特性和聚合物产物的特性，例如聚合产率和聚合物分子量。过渡金属催化剂组分的特征公式为：其中M为4-11族过渡金属，n为1-3的整数，Q为卤素或C1-C2烷基，PY为通过吡啶基的氮原子与M配位的吡啶基。进一步，关于公式（I），A为甲基基团、苯基或取代苯基，B和B2是相同或不同的芳香族基团，具体取决于催化剂组分的对称性。催化剂组分和激活的共催化剂组分在聚合反应区域与乙烯接触，在聚合条件下进行反应，该条件下没有氢气或含有少于乙烯的5摩尔%的氢气，以产生聚合物产物，可以是乙烯均聚物或乙烯和C3+α烯烃的共聚物，特别是乙烯-丙烯共聚物。
