| 英文摘要 | The copolymerization of ethylene and 5-ethylidene-2-norbornene (ENB) catalyzed by metallocene atalysts system is reported in this paper. The catalysts include Et(Ind)□ZrCl□/MAO and Cp□ZrCl□/MAO. The resulting copolymer contains an ethylidene group which can be readily converted to a hydroxyl group by hydrogen borane. Then the hydroxyl group in turn can be utilized for grafting with ε-caprolactone. The dependence of the graft weight percentage on the reaction time was also studied. The graft copolymer is a compatibilizer for various polyethylene blends with engineering plastics. A functional polyethylene can be easily synthesized by the copolymerization of ethylene and 9- decen-l-d using a homogeneous catalytic system of Et(Ind)□ZrCl□/MAO. The resulting functional polyethylene was characterized by NMR, DSC, IR and TGA; andcan also be utilized for grafting with ε-caprolactone. The grafted copolymer is also an effective compatibilizer. |
