✦ Synopsis

Copolymers of styrene and a styrene derivative having a Cs symmetrical ligand moiety were synthesized and used as the carrier for the synthesis of supported-type zirconocene catalysts. Propene polymerization was conducted using the resulting catalyst together with methylalumoxane (MAO), which gave syndiotactic l polypropene. The productivity of the polymer-supported catalyst (4010kg PP (mol Zr)-for 24h) was, however, very low compared to that of the corresponding homogeneous catalyst (9130 kg PP (mol Zr) -l for 20 rain).

Monocyclopendienyltitanium trichloride (CpTiCl 3 ) was supported on polymer carriers with different hydroxyl contents, and the supported catalysts were used for styrene polymerization. The supported catalysts exhibited high activity even at low Al/Ti ratios and increased the molecular weight of the
