A METHOD TO PRODUCE A WELL-DISPERSED MGO NANOPARTICLE-BASED ZIEGLER-NATTA CATALYST, AND USAGE IN PRODUCING ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE

摘要

Provided are a novel Ziegler-Natta catalyst and a novel UHMWPE produced using the one thereof. Mixing MgO nanoparticles, a hydrocarbon solvent, and a surfactant produces the well-dispersed MgO nanoparticle-based Ziegler-Natta catalyst. Contacting the obtained well-dispersed MgO nanoparticles with titanium tetrachloride (TiCl₄) produces a well-dispersed MgO nanoparticle-based Ziegler-Natta catalyst. Ethylene is polymerized in the presence of the well dispersed MgO nanoparticle-based Ziegler-Natta catalyst, thereby UHMWPE micro-fine powder, which has less than 5pm in particle diameter, excellent fusibility, and less particulate chlorine residual volume, is produced.
