Abstract:
The slurry and gas-phase polymerization of ethylene catalyzed by silica-supported bis(imino)pyridine complexes of ferrous chloride with ligands, such as 2,6-bis[1-(2-methyl-6-cyclohexylphenylimino)ethyl]pyridine (1), 2,6-bis[1-(2,4-dimethyl-6-cyclohexylphenylimino)ethyl]pyridine (II), 2,6-bis[1(2-methyl-6-cyclooctylphenylimino)ethyl]pyridine (M), 2,6-bis[1-(2,4-dimethyl-6-cyclooctylphenylimino)ethyl]pyridine (IV), and 2,6-bis[1-(2,4-dimethyl-6-cyclododecylphenylimino)ethyl]pyridine (V), and bisimines of nickel bromide with ligands, such as 1,2-bis(2-cyclopentyl-6-methylphenylimino)acenaphthene] (VI), 1,2-bis(2-cyclopentyl-4,6-dimethylphenylimino)acenaphthene] (VU), and 1,2-bis(2-cyclohexyl-6-methylphenylimino)acenaphthene] (VIII) was studied. Methylaluminoxane was used as a cocatalyst. In polymerization initiated by supported catalysts I-V, triisobutylaluminum was employed as an activator, while in the case of catalysts VI-VIII, polymerization proceeded without any cocatalyst. The studied heterogeneous catalytic systems were found to be close to the analogous homogeneous catalysts with respect to their activity and structure of the resulting polyethylene.
