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

Abstract

Superior to the homogeneous catalyst or physisorbed catalyst system is a system with the ansa-metallocene catalyst [{C₂ H₄ (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.
