摘要

Melting of different components in ethylene homopolymer produced at 25 ºC with the bis(imino)pyridyl complex of CoCl

activated with a combination of Al(C2H5)2Cl and Mg(C

)

Abstract

The article describes ethylene polymerization reactions with transition metal catalysts based on complexes of CoCl

and FeCl

with an

-tridentate ligand 2

6-bis[1-(2

6-dimethylphenylimino)ethyl]pyridine. The complexes are converted into polymerization catalysts by reacting them either with polymethylalumoxane (MAO) or with a combination of Al(C

)

Cl and Mg(C

)

at an [Al]:[Mg]

ratio of ~3. Both MAO-activated complexes readily polymerize ethylene at 35 °C with the formation of linear

low molecular weight polymers with a narrow molecular weight distribution. The same complexes

when activated with the Al(C

)

Cl-Mg(C

)

combination

form multi-center catalysts and generate polyethylenes with a broad molecular weight distribution.
