Summary A novel unbridged metallocene complex, (1-tol Ind) 2ZrCl2 (Tol=p-C6H4CH3) was prepared. Meso-like (1-Tol Ind) 2ZrCl2 afforded a syndiotactic-dominant polypropylene having a short syndiotactic length at low temperatures (-30°C). This stereosequence is due either to a weakly chain-end controlled or to a syndiotactic site controlled polymerization with site isomerization. Racemic isomer produced a completely atactic pp even at-30°C.
