摘要:A catalyst system includes a metallocene compound having the formula R 9 L 1 L 2 M 1 R 1 R 2 wherein R 9 is a bridge between ligands L 1 and L 2 and M 1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R 1 and R 2 can be hydrogen or aliphatic or aromatic groups. Bridge R 9 can include silicon, germanium or tin. The metallocene compound of the invention as synthesized has a racemic to meso isomer ratio of greater than 5 to 1, thereby precluding the need for subsequent separation of the meso isomer.
