What is Polymerization of propene with highly isospecific. SiO~2~‐supported zirconocene catalysts activated with common alkylaluminiums about?

## 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.
