  New Bis(arylimino)pyridyl Complexes as Components of Catalysts for Ethylene Polymerization

  摘要：

  A new series of 2,6-bis(arylimino)pyridineiron(II) complexes with cycloaliphatic (cyclopentyl, cyclohexyl, cyclooctyl, and cyclododecyl) substituents in the ortho position of the aryl ring are synthesized and studied as comp orients for ethylene polymerization catalysts. Methylaluminoxane is used as an activator for the complexes. The resulting catalytic systems are more active in polymerization at elevated temperatures (60-80degreesC) than previously described systems based on substituted 2,6-bis(arylimino)pyridines. The influence of the number of CH2 groups in a cycloaliphatic substituent on the efficiency of the catalytic system is studied. Polymers formed are characterized by an increased molecular weight, high density, and high crystallinity.
