AI Technical Summary
Technical Problem
Conventional methods for preparing cocatalyst compounds often result in the presence of moisture, which inhibits the activity of transition metal catalysts used in polymerization reactions.
Method used
A method for preparing a cocatalyst compound using an anhydrous hydrocarbon solvent, which prevents the inclusion of water and allows for the synthesis of a cocatalyst that effectively activates transition metal catalysts, particularly hafnium compounds, enhancing their activity and stability.
Benefits of technology
The cocatalyst prepared by this method shows improved catalyst activity and stability, leading to efficient polymerization reactions with increased reproducibility and reduced catalyst usage, thereby enhancing technical and cost competitiveness.
