| titleOfInvention | Preparation method for propylene polymer and propylene polymer prepared by using same |
| abstract | The invention provides a preparation method for a propylene polymer and a propylene polymer prepared by using the same. The preparation method for the propylene polymer comprises the following steps of: under a polymerization reaction condition, undergoing a first contact reaction on a propylene-containing olefin reaction raw material, an olefin polymerization catalyst and a first external donor component in a first reactor; undergoing a second contact reaction on a mixture obtained in the first contact reaction and a second external donor component in a second reactor, wherein the first external donor component is different from the second external donor component, and the molar ratio of the second external donor component to the first external donor component is larger than 9. Due to the adoption of the method provided by the invention, a propylene polymer with a high melt flow speed, high melt strength and wide molecular weight distribution can be obtained, and the propylene polymer is suitable for serving as a coating. |
