Polymerization process for making a polyethylene nanocomposite

Methods of preparing high-density polyethylene (HDPE) nanocomposites by in situ polymerization with a zirconocene catalyst, a methylaluminoxane cocatalyst, a calcium zirconate nanofiller in a solvent. The calcium zirconate nanofiller, which is dispersed across the polyethylene matrix, is found to en...

Zusammenfassung:	Methods of preparing high-density polyethylene (HDPE) nanocomposites by in situ polymerization with a zirconocene catalyst, a methylaluminoxane cocatalyst, a calcium zirconate nanofiller in a solvent. The calcium zirconate nanofiller, which is dispersed across the polyethylene matrix, is found to enhance catalyst activity, and other properties of the HDPE nanocomposites produced, including but not limited to flame retardancy, crystallinity and surface morphology.
