Abstract
The present invention relates to a novel metallocene catalyst compound for the production of a polyolefin resin having a high molecular weight and a wide molecular weight distribution or a method of preparing the same, and more particularly to a metallocene catalyst compound using a ligand containing a Group 15 or 16 element having a bulky substituent or a method of preparing the same. The present invention provides a novel metallocene catalyst compound represented by Chemical Formula 1 below. (L1){(N-L2)Z1(Y)Z2(N-L3)}(X)M [Chemical Formula 1]
Claims9
