  Vinyl-addition polymerization of norbornene catalyzed by (pyrazol-1-ylmethyl)pyridine divalent iron, cobalt and nickel complexes

  摘要：

  Complexes of 2-((3,5-dimethyl)-1H-pyrazol-1-ylmethyl)pyridine (L1), 2-((3,5-ditert-butyl-1H-pyrazol-1-yl)methyl)pyridine (L2), 2-((3,5-diphenyl)-1H-pyrazol-1-yl)methyl)pyridine (L3), 2-((3,5-bis(trifluoromethyl)-1H-pyrazol-1-ylmethyl)pyridine (L4) and 2,6-bis(3,5-dimethyl-1H-pyrazol-1-y1)methyl) pyridine (L5) with cobalt(II), iron(II) and nickel(II), Ni(L1)Cl-2 (1), Co(L1)Cl-2 (2), Fe(L1)Cl-2 (3), Ni(L2)Cl-2 (4), Ni(L3)Cl-2 (5), Co(L3)Cl-2 (6), Fe(L3)Cl-2 (7), Ni(L4)Cl-2 (8) and Ni(L5)Cl-2 (9), were used as catalyst precursors to produce vinyl-addition type norbornene polymers. Both the identity of the metal center and nature of ligand affected the polymerization behaviour of the resultant catalysts. Nickel catalysts were generally more active than the corresponding iron and cobalt analogues. The polynorbornene produced have high molecular weights (0.5-2.1 x 10(6) g/mol) and narrow molecular weight distributions. Analyses of polymer microstructure using NMR and IR spectroscopy confirmed the polymers produced to be vinyl-addition polynorbornene. (C) 2011 Elsevier Ltd. All rights reserved.
