Abstract

Several types of SiO~2~‐supported metallocene catalysts were prepared using chemically modified silica gel. Polymerization of propene was conducted with these catalysts combined with methylaluminoxane (MAO) or ordinary alkylaluminiums. Highly isotactic poly(propylene) with high molecular weight was obtained by the catalysts whose zirconocene ligands were chemically immobilized on SiO~2~. The preparative methods of these catalysts and the results of propene polymerization, together with the analytical data of produced polymers, are reported in some detail.

## Abstract Summary: Stopped‐flow polymerization of propene was first conducted at 40 °C using the TiCl~4~/DBP/MgCl~2~ catalyst (DBP = dibutyl phthalate) combined with Al(C~2~H~5~)~3~. An induction period was observed at the beginning of polymerization, and the resulted polymer contained a consider
