| titleOfInvention | Procatalysts for Olefin Polymerization Containing Specific Ratios of Internal Donor of Aminobenzoate and Internal Donor of 1,3-Diether |
| abstract | The present invention relates to a method for preparing a procatalyst for olefin polymerization, the method comprising combining a magnesium-containing support with a halogen-containing titanium compound, a first internal electron donor represented by formula A, a A second internal electron donor is contacted with an 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 hydrogen or hydrocarbyl; 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 hydrocarbyl; 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. |
