Abstract: To obtain a novel support with practical value for metallocene catalyst(ηC5H5)TiCl3(CpTiCl3), poly(styrene-co-4-vinyl-pyridine)/SiO2 nanoscale hybrid material(SrP/SiO2) was firstly produced as support. After pretreatment by methylaluminoxane(MAO), the hybrid materials reacted with CpTiCl3. The results from SAXS, SEMand TEMindicated the morphology and structure of organic/inorganic hybrid materials, and the size of inorganic particle in hybrid was nanoscale. The results from IRand XPS-showed that there were two possible cationic active species in the hybridsupported catalyst, the polymerization results of styrene proved this possibility.
