| titleOfInvention |
Metallocene ligands, metallocene compounds and metallocene catalysts, their synthesis and their use for the polymerization of olefins |
| abstract |
A catalyst system includes a metallocene compound having the formula R9 L1 L2 M1 R1 R2 wherein R9 is a bridge between ligands L1 and L2 and M1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R1 and R2 can be hydrogen or aliphatic or aromatic groups. Bridge R9 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. |
