  • STORAGE STABLE METALLOCENE SOLUTIONS AND USES THEREOF IN CATALYST SYSTEMS FOR ETHYLENE POLYMERIZATION
    Publication number: 20260109792
    Abstract: Metallocene solutions containing trimethylaluminum, a C4-C8 alkane solvent, and a metallocene compound in an amount from 0.2 to 8 mg per mL of the metallocene solution are described. Catalyst compositions incorporating these metallocene solutions plus an activator-support and an organoaluminum compound can be utilized in polymerization processes to produce polyethylene products.
