Method for Preparing Catalyst for Polymerizing Conjugated Diene, Catalyst and Method for Preparing Conjugated Diene-Based Polymer Using the Same |
| abstract |
A method for preparing a catalyst for use in polymerizing a conjugated diene-based monomer, the catalyst, and a method for preparing a conjugated diene-based polymer using the same are disclosed herein. In an embodiment, a method of preparing a catalyst comprises mixing a lanthanide rare earth element-containing compound, an alkylating agent compound and a halogen compound in the presence of a solvent to prepare a catalyst composition, adding a conjugated diene-based monomer to the catalyst composition to form a preformed catalyst composition, and aging the preformed catalyst composition at a temperature of −1° C. to −15° C. for 3 hours to 98 hours to prepare the catalyst. The catalyst has excellent catalyst activity and polymerization reactivity and is useful for preparing a conjugated diene-based polymer which has an excellent modification ratio and improved compounding properties. |
