| 英文摘要 | Branched polyethylene from ethylene as single monomer was prepared by the tandem catalyst system of 12-[2-Me C6H4N=(Me)](2)C5H3N}FeCl2 (1) and {2,6-[1-(2,6-Me-2-4-Br-C6H4N=(Me)](2)C5H3N FeCl2 (2) activated with methylaluminoxane (MAO) The products of polymerization were characterized by DSC, GPC and C-13-NMR. The results revealed that the copolymer produced by in situ copolymerization of ethylene was a mixture of branched polyethylene and alpha-olefin. The content of alpha-olefin in the mixture was increased with increasing the molar ratio of catalysts 1/2. The MWD parameters of polyethylene and copolymer were 28.6 and 7.9, respectively. C-13-NMR spectra showed that there were ethyl groups, butyl groups and long chain alkyl groups in the copolymer. The average degree of branching of such branched polyethylene was less than 5C/1000C. |
