Abstract
Provided are a novel metallocene compound, a metallocene-supported catalyst, and a method of preparing a polyolefin using the same. The metallocene-supported catalyst according to the present disclosure exhibits a high polymerization activity even when the metallocene compound is supported on a support, thereby showing an excellent activity and preparing a polyolefin having a high molecular weight.
