How to produce polydienes |
| abstract |
A method for preparing a polymer is described that uses a lanthanide-based coordination catalyst and uses a reduced amount of Lewis base to terminate the polymerization while retaining the reactivity of the polymer chain end to the functionalizing agent. The The Lewis base is a meso-enriched oxolanyl Lewis base. The resulting functionalized polymer has a higher purity and can be used in products such as tires. |
