Nickel alpha-Keto-beta-Diimine Initiators for Olefin Polymerization
(WILEY-V C H VERLAG GMBH, 2009)
(Figure Presented) A new ligand-metal combination (see picture, Ni green, Br brown, N blue, O red, C gray) was designed to be cationic and to benefit from removal of electron density by the action of a Lewis acid on the ...
Nickel pre-catalysts bearing [(N)-imidoylamidine] ligands; influence of the presence of pyridine and pentafluorophenyl groups in ligand backbone on the reactivity in ethylene polymerizations
(Elsevier, 2012)
In this contribution the synthesis and polymerization activity of the nickel complexes [NiBr2{N0-(2,6-
diisopropylphenyl)-N-[1-(2,6-diisopropylphenylimine)ethyl]-N-(2,3,4,5,6-pentafluorophenyl)acetam
idine}] (2), ...
Mono and bimetallic nickel bromide complexes bearing azolate-imine ligands: Synthesis, structural characterization and ethylene polymerization studies
(ELSEVIER SCIENCE SA, 2009)
The synthesis of N-(1-(3,5-dimethylpyrazol-1-yl)ethylidene)-2,6-diisopropylaniline (1) and N-(1-(indazol-2-yl)ethylidene)-2,6-diisopropylaniline (2) allowed access to new transition metal complexes. When reacted with ...
Partial oxidation of methane on NiO-MgO-ZrO2 catalysts
(ELSEVIER SCI LTDOXFORD, 2012)
Catalysts containing mixtures of NiO, MgO and ZrO2 were synthesized by the polymerization method. They were characterized by X-ray diffraction (XRD), physisorption of N-2 (BET), X-ray photoelectron spectroscopy (XPS) and ...
Synthesis and properties of branched polyethylene/high-density polyethylene blends using a homogeneous binary catalyst system composed of early and late transition metal complexes
(Wiley-Blackwell, 2002-10-18)
Branched polyethylene/high-density polyethylene blends (BPE/HDPE) with a wide range of molecular weights, melt flow indexes (MFI), and intrinsic viscosity were prepared using the homogeneous binary catalyst system composed ...

Carbon dioxide reforming of ethanol over Ni/Y(2)O(3)-ZrO(2) catalysts
(ELSEVIER SCIENCE BV, 2009)
Supported nickel catalysts of composition Ni/Y(2)O(3)-ZrO(2) were synthesized in one step by the polymerization method and compared with a nickel catalyst prepared by wet impregnation. Stronger interactions were observed ...
