Ziegler-natta catalyst for olefin polymerization, method of manufacturing polyolefin and polyolefin resin

Abstract

The present invention provides a Ziegler-Natural catalyst for olefin polymerization, a method for manufacturing polyolefins, and a polyolefin resin, wherein the Ziegler-Natural catalyst for olefin polymerization comprises (i) a Ziegler-Natural pre-catalyst for olefin polymerization, comprising a titanium compound represented by chemical formula 1, a magnesium compound represented by chemical formula 2, and an internal electron donor represented by chemical formula 3; (ii) an organoaluminum compound represented by chemical formula 4; and (iii) an external electron donor represented by chemical formula 5, wherein the molar ratio of the internal electron donor to the external electron donor is from 1:0.07 to 1:0.09. The present invention provides a Ziegler-Natta catalyst for olefin polymerization, a method of manufacturing a polyolefin, and a polyolefin resin, wherein the Ziegler-Natta catalyst for olefin polymerization includes (i) a Ziegler-Natta pro-catalyst for olefin polymerization including a titanium compound represented by Chemical Formula 1, a magnesium compound represented by Chemical Formula 2, and an internal electron donor represented by Chemical Formula 3; (ii) an organoaluminum compound represented by Chemical Formula 4; and (iii) an external electron donor represented by Chemical Formula 5, wherein the internal electron donor and the external electron donor are included in a molar ratio of 1:0.07 to 1:0.09.
