Abstract: Activities during ethylene/1-hexene copolymerization were found to increaseusing the mixed titania/silica-supported MAO with rac-Et[Ind]2ZrCl2 metallocenecatalyst. Energy Dispersive X-ray spectorcopy (EDX) indicated that the titania wasapparently located on the outer surface of silica and acted as a spacer to anchor MAO tothe silica surface. IR spectra revealed the Si-O-Ti stretching at 980 cm-1 with low contentof titania. The presence of anchored titania resulted in less steric hindrance and lessinteraction due to supporting effect.
