Method for polymerizing ethylene using BaFe12O19 nanoparticles, and a polyethylene-barium ferrite nanocomposite made therefrom

摘要

A method involving polymerizing ethylene in the presence of a catalyst composition containing BaFe₁₂O₁₉ nanoparticles, a zirconocene catalyst, and an alkylaluminoxane co-catalyst. A nanocomposite is formed by the polymerization, whereby the BaFe₁₂O₁₉ nanoparticles are dispersed in a matrix of polyethylene (PE), and the % crystallinity is lowered. The activity of the catalyst is increased in the presence of the BaFe₁₂O₁₉ nanoparticles.
