    摘要: 본발명은아미도그룹이도입된모노시클로펜타디에닐리간드가배위된전이금속화합물의새로운제조방법에관한것이다. 본발명에따른전이금속화합물의제조방법은중간체인아민계화합물을제조하는단계에서케톤계화합물과함께염화리튬(LiCl)을사용함으로써전이금속화합물의제조가간편할뿐만아니라, 후처리단계에서염화리튬(LiCl)의제거가용이하여별도의필터단계를필요로하지않는다.

    摘要: PURPOSE: An ethylene-alphaolefin copolymer is provided to enable the production using a catalyst composition including transition metal compounds and to ensure ultralow density, narrow molecular weight distribution, and high molecular weight. CONSTITUTION: An ethylene-alphaolefin copolymer is prepared by a composition including a transition metal compound represented by chemical formula 1. In the ethylene-alphaolefin copolymer, (i) density is 0.85~0.92 g/cm^3, (ii) average molecular weight is 100,000~150,000, (iii) molecular weight distribution(Mw/Mn) is 2~3, and (iv) melt index at 2.16 kg load is more than O and 1 g/10min or less.
