摘要:
A procatalyst carrier system which includes one or more paraffinic solvents, one or more paraffin-insoluble procatalysts, and optionally one or more cocatalysts wherein the carrier system is in the form of a slurry is provided. Also provided is a process including selecting one or more paraffin-insoluble organometallic procatalysts; adding the one or more procatalysts to a sufficient quantity of paraffmic solvent to form a slurry of the one or more procatalysts in the paraffmic solvent; introducing one or more first cocatalysts into a polymerization reactor; and introducing the slurry into the polymerization reactor; a reaction product of the process and articles made from the reaction product.
