Abstract:
A preparation method of a catalyst for polyolefin polymerization capable of polymerizing low-density polyethylene in a single reactor without separately injecting a comonomer to thereby prepare a final product with a low cost through a more simplified process, a catalyst obtained by the preparation method, and a preparation method of a polyolefin using the catalyst are provided.
