Abstract

The unsymmetrical allyl containing post-metallocene complex [ArN=C(Me)][Ar'N=C(Me)]C~5H~3NFeCl~2 [Ar=2, 6-(i-Pr)~2C~6H~3, Ar'=4-allyl-2, 6-(i-Pr)~2C~6H~3](3) has been prepared and characterized. Complex (3) can be co-polymerized with styrene in the presence of radical initiator to produce polymerized post-metallocene catalyst which exhibits high activity for ethylene polymerization (2.5×10^6 g PE/mol Fe.h).

Key words: METALLOCENES, IRON COMPLEX, POLYMERISATION CATALYST, OLEFINIC POLYMERIZATION, SUPPORTED CATALYST, POLYOLEFINE
