Metallocene ligands, metallocene compounds and metallocene catalysts, their synthesis and their use for the polymerization of olefins
A catalyst system includes a metallocene compound having the formula R L L M R R , wherein R is a bridge between ligands L and L and M is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R and R can be hydrogen or aliphatic or aromatic groups. Bridge R can inclu...

| description | A catalyst system includes a metallocene compound having the formula R L L M R R , wherein R is a bridge between ligands L and L and M is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R and R can be hydrogen or aliphatic or aromatic groups. Bridge R 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. |
