Novel Aluminoxanes Prepared from AlEt3/Al(i-Bu)3 Mixture as Cocatalyst for Metallocene Catalyzed Ethylene Polymerization
摘要:
Aluminoxanes containing both ethyl and wo-butyl groups were synthesized by the hydrolysis of Al(C2H3)3 (TEA)/A1(i-C4H9)3 (TIBA) mixtures. The aluminoxane made from the TCA/TIBA mixture of molar ratio 7:3 showed cocatalyst activity of about five times as those of ethylaluminoxane or isobutylaluminoxane for ethylene polymerization catalyzed by Cp2ZrCl2. The aluminoxane was characterized and the possible reasons for its high activity were discussed.
