The present invention relates to a prepolymerized olefin polymerization catalyst, a polymerization method of olefins using the same, and a polyolefin prepared by the same, wherein a Ziegler-Natta catalyst is prepolymerized by using α-olefin and vinyl cyclic saturated hydrocarbon in stages. Thereafter, the polyolefin may be prepared in high yield by polymerizing the olefin using the prepolymerized Ziegler-Natta catalyst, and the polymerized polyolefin may have high stereoregularity, high volume density, and high crystallinity. . |
