Abstract

Provided are a Ziegler-Natta catalyst for olefin polymerization, a method for preparing polyolefin, and a polyolefin resin. The Ziegler-Natta catalyst comprises: (i) a Ziegler-Natta pro-catalyst for olefin polymerization comprising a titanium compound represented by Formula 1, a magnesium compound represented by Formula 2, and an internal electron donor; (ii) an organoaluminum compound represented by Formula 7; and (iii) an external electron donor represented by Formula 3, wherein the internal electron donor includes a mixture of a first internal electron donor represented by Formula 4, a second internal electron donor represented by Formula 5, and a third internal electron donor represented by Formula 6, the mole ratio of the external electron donor to the mixture ranging from 115 to 130.
