摘要

Abstract

The composite

prepared with polypropylene grafting maleic anhydride and silica crosslinked by 3-aminopropyltriethyoxysilane

was used as the carrier to support titanium chloride．XPS and FTIR measurements were emplyed to investigate the states of several atoms during stepwise supporting catalyst for clarifying the mechanism．The results showed two possible mechanisms of active catalytic sites on the composite carrier：the catalytic sites bridged through MAO on the inorganic silica-gel；on contrary

the catalytic sites bridging with carbonyls of amide formed in the composite．
