Ethylene/Styrene Copolymerization by (Me₃SiC₅H₄)TiCl₂(O-2,6-ⁱPr₂-4-RC₆H₂) (R = H, SiEt₃)-MAO Catalysts: Effect of SiMe₃ Group on Cp for Efficient Styrene Incorporation.

ABSTRACT: The synthesis and structural analysis of (Me₃SiC₅H₄)TiCl₂(OAr) [OAr = O-2,6-ⁱPr₂-4-RC₆H₂; R = H, SiEt₃] revealed that it exhibits higher catalytic activities than (^tBuC₅H₄)TiCl₂(OAr), Cp*TiCl₂(OAr), with efficient comonomer incorporation in ethylene/styrene copolymerization in the presence of a methylaluminoxane (MAO) cocatalyst. The catalytic activity in the copolymerization increased upon increasing the charged styrene concentration along with the increase in the styrene content in the copolymers, whereas the activities of other catalysts showed the opposite trend.
