摘要： 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.

摘要： There is disclosed a catalyst composition for the polymerization of olefins, particularly alpha-olefins. The composition is prepared by synthesizing a catalyst precursor and then combining it with a conventional catalyst activator. The precursor is synthesized by: (a) contacting a solid, porous carrier with an aluminum compound; (b) contacting the resulting product with a mixture of vanadium and titanium compounds; (c) contacting the product with an alkyl ether and (d) pre-activating the product of step (c) with a mixture of a halogenating agent and an aluminum compound.The catalyst composition is used without a halogenating agent in the polymerization medium to produce narrow molecular weight distribution HDPE and LLDPE products, or with a halogenating agent in the polymerization medium to produce broad molecular weight distribution LLDPE and HDPE products.
