Abstract
Provided are a bridged metallocene compound particularly suitable for copolymerization of ethylene and alpha-olefin or cyclic olefin, a process of preparing the metallocene compound, and a process of preparing polyolefin using the metallocene compound. The bridged metallocene compound has low steric hindrance and good (co)polymerization activity, and thus, exhibits good activity in copolymerization of ethylene and alpha-olefin such as 1-hexene or 1-octene. Furthermore, the process of preparing the bridged metallocene compound is simplified, and thus, suitable for mass production.
