Abstract:
The present invention provides a method for preparing a supported metallocene catalyst, a supported metallocene catalyst prepared by the method, and a method for preparing a polyolefin using the supported metallocene catalyst. The supported metallocene catalyst according to the present invention contains catalyst components uniformly distributed deep into the whole porous carrier particles to secure a high catalytic activity and facilitates polymerization of polyolefins with high bulk density.
