| 中文摘要 | novel chromium catalysts based on bidentate phenoxy-phosphinoyl (ho-2r(1)-4r(2)-6(ph2p=o)c6h2: r-1 = r-2 = h, 3a; r-1 = tbu, r-2 = h, 3b; r-1 = r-2 = tbu, 3c; r-1 = r-2 = cumyl, 3d; r-1 = anthracenyl, r-2 = h, 3e) and thiophenol-phosphine (hs-2r(1)-4r(2)-6(ph2p)c6h2: r-1 = r-2 = h, 4a; r-1 = sime3, r-2 = h, 4b) were prepared and characterized. treatment with modified methyaluminoxane, these catalysts displayed moderate to high-catalytic activities for ethylene polymerization. the activities of them were higher than those of the corresponding catalysts based on bidentate phenoxy-phosphine ligands. both the coordinated donors and the ortho-substituent of the ligands played an important role in improving catalytic activity. the effects of reaction parameters, such as cocatalyst and al/cr molar ratio as well as reaction temperature, on ethylene polymerization behaviors were investigated in detail for two favorable catalytic systems, 3b/crcl3(thf)(3) and 4b/crcl3(thf)(3). catalyst 4b/crcl3(thf)(3) displayed higher catalytic activity and better temperature tolerance for ethylene polymerization than 3b/crcl3(thf)(3).
