Abstract
The present invention relates to a novel group 4 transition metal compound, a method for preparing the compound, a catalyst composition containing the compound, and a method for preparing a polyolefin, comprising a step for forming a polymerization reaction of olefin monomers in the presence of the catalyst composition. The group 4 transition metal compound of the present invention exhibits an excellent catalytic activity and has excellent thermal stability in a polyolefin synthesis reaction, and thus can be used even in a polyolefin synthesis reaction at a high temperature. In addition, the compound of the present invention can be advantageously used in the synthesis process of grade-controlled polyolefin since the weight average molecular weight of the synthesized polyolefin and the octane content in the polymer can be adjusted by varying the kinds of center metal and ligand.
