RISComparative ethylene polymerization via imino-quinolinol catalysts
Abstract—A series of zirconium catalysts based on tridentate 8-hydroxyquinoline Schiff base ligands were prepared and successfully used for polymerization of ethylene. The highest activities of the prepared catalysts were ...
Synthesis of polyethylene and PE/MWCNT composite using a spherical bulky a-diimine Pd(II) catalyst
The ligand N,N-bis(2,6-dibenzhydryl-4-ethoxy phenyl)butane-2,3-diimine via a multi-step reaction and the correspond palladium(II) a-diimine catalyst were synthesized, characterized and used in polymerization of ethylene. ...
Single and binary catalyst systems based on nickel and palladium in polymerization of ethylene
systems in ethylene polymerization. In a study of the catalyst systems, the average molecular weight and molecular weight distribution for the binary polymerization were between those for the individual catalytic polymerizations; however, the binary...
Novel synthesized binuclear Ni-based catalysts for ethylene polymerization
Two Novel synthesized binuclear catalysts were resulted which effect of ortho substituent on A1 and A2 catalyst activity was studied. There is optimum molar ratios of about [Al]:[Ni] = 1500:1 for catalyst A1 to reach the ...

Practical and Theoretical Study on the α- Substituent Effect on α- Diimine Nickel (II) and Cobalt (II)- Based Catalysts for Polymerization of Ethylene 1
The Late transition metal catalysts based on Ni(II) and Co(II) were synthesized and their structure and activity in polymerization of ethylene were compared. Methylaluminoxane (MAO) was used as a co-catalyst. To discover ...
Thermal and morphological properties of polyethylene reactor alloys using ZN/BLTM catalytic system
To study on the effect of counterpart catalyst on the final produced polyethylene properties, the polymerizations were carried out under similar condition for catalyst mixing and each catalyst, solely. In this system, each ...
