Polymerization processes for the production of cis-1,4-polydienes |
| abstract |
A process for preparing a polydiene, the process comprising (i) preparing an active catalyst composition by combining a rare-earth compound including a rare-earth metal, an alkylating agent, an aluminoxane, and optionally a halogen-containing compound, where the catalyst composition includes halogen at molar ratio to the rare-earth metal of from about 0.5:1 to about 2.0:1; and (ii) introducing the active catalyst composition to conjugated diene monomer. |
