Patent number: 8541520Abstract: The method of making high-density polyethylene with titania-iron nanofillers involves mixing a TiO2/Fe titania-iron nanofiller with a vanadium (III) complex bearing salicylaldiminato ligands polymerization catalyst in a reactor. The reactor is then charged with toluene and heated to a temperature of about 30° C. Following heating, ethylene is fed into the reactor at a fixed pressure, and a methyl aluminum dichloride cocatalyst is added to initiate in situ polymerization. Polymerization is quenched to yield high-density polyethylene with titania-iron nanofillers, which is then washed and dried. Through the addition of a TiO2/Fe nanofiller, the molecular weight, the crystallinity and the melting temperature of high-density polyethylene are all increased, while the polydispersity index (PDI) is decreased.Type: GrantFiled: January 21, 2013Date of Patent: September 24, 2013Assignee: King Fahd University of Petroleum and MineralsInventors: Mamdouh Ahmad Al-Harthi, Omer Yahya Bakather, Sadhan Kumar De, Reyad Awwad Khalaf Shawabkeh
