摘要: The supported metallocene catalyst for olefin polymerization is (nBuCp)2ZrCl2 impregnated onto a silica support having MAO tethered thereon. The catalyst is made by dehydroxylating silica, adding MAO dropwise to a slurry of the silica in toluene, heating the mixture for several hours, reacting (nBuCp)2ZrCl2 in toluene solvent with the MAO/silica support, and drying the catalyst under vacuum. The catalyst may be used, e.g., to catalyze copolymerization of ethylene with 1-hexene.

摘要: The supported metallocene catalyst for olefin polymerization is (nBuCp)2ZrCl2 impregnated onto a silica support having nBuSnCl3 and MAO tethered thereon. The catalyst is made by dehydroxylating silica, forming a silica/toluene slurry, injecting nBuSnCl3 into the slurry, refluxing the silica/toluene/nBuSnCl3 slurry, adding MAO dropwise to a slurry of the nBuSnCl3-functionalized silica in toluene, heating the mixture for several hours, reacting (nBuCp)2ZrCl2 in toluene solvent with the MAO/nBuSnCl3-functionalized silica support, and drying the catalyst under vacuum. The catalyst may be used, e.g., to catalyze copolymerization of ethylene with 1-hexene.
