Abstract: Ethyl-(iso-butyl) aluminoxane(EBAO) was synthesized and characterized by UV Visible spectrum. The four absorption peaks of UV Visible spectrum of EBAOwere assigned to the different sequence distributions of alkyl groups of EBAO. Ethylene copolymerization by Et(Ind)2ZrCl2/EBAOand MAOwas investigated. The interaction between metallocene and aluminoxanes was monitored by UV-Visible spectra. It was found that EBAOwould form looser ion pair than MAOand accounted for the high comonomer incorporation of copolymers synthesized by EBAO.

Key words: Ethyl(iso-butyl)-aluminoxane(EBAO), UV-Visible spectrum, Ethylene polymerization
