| description | The invention relates to the technical field of polymer production, and discloses polypropylene and application thereof, and a method and a device for continuously preparing polypropylene. The method is carried out in a device containing at least two reaction kettles which are sequentially connected in series, and comprises the following steps: (1) in the presence of a catalyst I, introducing propylene or a first monomer composition containing propylene into the reaction kettle I, and carrying out a polymerization reaction to obtain a first material flow; and (2) in the presence of a catalyst II, introducing the first material flow and a second monomer composition into a reaction kettle II for contact reaction. The polypropylene prepared by the method can effectively solve the problems of poor rigid-tough balance performance and low notch impact strength of the polypropylene material, and the prepared polypropylene material is uniform in phase state, has the advantages of excellent rigid-tough balance perform |
