摘要： 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 retardency, crystallinity and surface morphology.

摘要： A method for preparing blends of at least two polymer components is described herein. The disclosed method generally involves controlling relative molecular weights and ratios of the two or more polymer components by selecting a first initiator, a second initiator, and a monomer, and subjecting the reactants to conditions suitable to polymerize the monomer based at least in part on the first and second initiators in connection with obtaining the polymeric blend. The second initiator is advantageously selected based on one or more characteristics associated therewith, based on a characteristic of the first initiator. A polymeric blend produced according to such a method is also provided herein.
