Abstract
Modification of ethyl-iso-butylaluminoxanes (EBAOs) with alkyl boronic acid resulted in different co-catalytic performances when combined with iron complexes for ethylene polymerization, in particular the preferred high-temperature performance. The changes in polymerization activity and molecular weight distribution of the resulting polymer derived from the variation of aluminoxane were investigated. The varying performance of the iron complex with different aluminoxanes has proved that the interaction between the late transition metal complex and aluminoxane greatly affects the performance of such bicomponent catalyst systems Copyright © 2003 Society of Chemical Industry
