The copolymerization of ethylene and 5-ethylene and 5-ethylidene-2-norbornene (ENB) catalyzed by metallocene catalysts system is reported in this paper. The catalysts include Et(Ind)2 ZrCl2/MAO and Cp2ZrCl2/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-decenl-ol using a homogeneous catalytic system of Et(Ind)2ZrCl/MAO. The resulting functional polyethylene was characterized by NMR, DSC, IR and TGA; and can also be utilized for grafting with ε-caprolactone. The grafted copolymer is also an effective compatibilizer. - 英文摘要: --
