| titleOfInvention | Procatalyst comprising specific ratio of aminobenzoate internal donor and 1,3-diether internal donor for olefin polymerization |
| abstract | The present invention relates to a method for preparing a procatalyst for olefin polymerization, the method comprising making a magnesium-containing carrier and a halogen-containing titanium compound, a first internal electron donor represented by formula A, a compound represented by formula B contacting the second internal electron donor with the activator; wherein the molar ratio of the first internal donor to the second internal donor is between 0.01 and 0.7; Wherein in formula A, each R 80 group is independently a substituted or unsubstituted aromatic group; R 81 , R 82 , R 83 , R 84 , R 85 , R 86 and R 87 are each independently selected from N is a nitrogen atom; O is an oxygen atom; and C is a carbon atom; wherein in formula B, R 51 and R 52 are each independently selected from hydrogen or a hydrocarbon group; R 53 and R 54 are each independently selected from hydrogen, halo, or hydrocarbyl; O is an oxygen atom; and C is a carbon atom. |
