Methylalumoxane MCM-41 as Support in the Co-Oligomerization of Ethene and Propene with [{C2H4(1-indenyl)2}Zr(CH3)2]

Superior to the homogeneous catalyst or physisorbed catalyst system is a system with the ansa‐metallocene catalyst [{C2H4(1‐ind)2}Zr(CH3)] on a support formed by covalently anchoring methylalumoxane (MAO) on the internal pore walls of MCM‐41. This system is a highly active and shape‐selective mesoporous host in the co‐oligomerization [shown schematically in Equation (a)] of ethene and propene with ansa‐metallocenes. TMA=trimethylaluminum, ind=indenyl.
