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