Title:
METHOD FOR PREPARING CATALYST COMPOSITION AND METHOD FOR PREPARING CONJUGATED DIENE-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/158211
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a catalyst composition for preparing a catalyst composition having improved catalytic activity by pre-treating a hydrogen-bonded lanthanum-based rare earth element compound and/or an oligomeric form of a lanthanum-based rare earth element compound that cause a decrease in catalytic activity, and to a method for preparing a conjugated diene-based polymer by using a catalyst composition prepared therefrom.
