Abstract

The polymerization of propylene was studied with a series of dinuclear early transition metal zirconocene-late transition metal complexes bridged by phosphido and arsenido moieties of general formula [(η⁵-C₅H₄R'')₂Zr{μ-ERR'}₂M(CO)(n)] (E = P, R = R' = SiMe₃, R''= H, M = Mo, n = 4 (1); E = P, R = R' = SiMe₃, R'' = H, M = Ni, n = 2 (2); E = As, R = R' = SiMe₃, R''= H, M = Cr, n = 4 (3); E = P, R = H, R' = 2,4,6-i-Pr₃C₆H₂, R''= Me, M = Mo, n = 4 (4); E = P, R = H, R' = 2,4,6-i-Pr₃C₆H₂, R''= Me, M = Cr, n = 4 (5)), as well as with the corresponding monometallic zirconocene precursor complexes of the type [(η⁵-C₅H₄R'')₂Zr(ERR')₂] (E = P, R = R' = SiMe₃, R'' = H (6); E = P, R = H, R' = 2,4,6-i-Pr₃C₆H₂, R'' = H (7)) and [(η⁵-C₅H₄Me)₂Zr(ERR')Cl] (E = P, R = H, R' = 2,4,6-i-Pr₃C₆H₂ (8)). The active cationic species were generated treating the complexes with an excess of methylalumoxane (MAO). The catalytic activity was found to be strongly dependent on temperature and catalyst/MAO ratio.
