摘要 |
The present invention provides a catalyst composition exhibiting, by including a lanthanide rare earth element-containing compound; modified methylaluminoxane; a halogen compound; and an aliphatic hydrocarbon-based solvent, excellent catalytic activity even with a small main catalyst amount, capable of preparing a conjugated diene-based polymer having excellent catalytic activity and thereby having high cis-1,4-bond content ratio, high linearity, and narrow molecular weight distribution, and capable of reducing polymerization reaction time, and a method for preparing the same. |
