| titleOfInvention | A kind of olefin batch polymerization process |
| abstract | The invention belongs to the field of olefin polymerization, and specifically provides an olefin batch polymerization process. The process includes: 1) adding a main catalyst, an activator and an optional external electron donor into a pre-complexing reaction kettle to carry out a pre-complexing reaction , to obtain a pre-complexed catalyst; 2) adding the pre-complexed catalyst and the olefin for pre-polymerization into the pre-polymerization reactor to carry out a pre-polymerization reaction to obtain a pre-polymerized catalyst; 3) adding the pre-polymerized catalyst and the olefin for polymerization to the pre-polymerized catalyst It is added into the polymerization kettle to carry out the polymerization reaction to obtain the polyolefin. In the olefin batch polymerization process of the present invention, a pre-complexation reaction kettle and a pre-polymerization reaction kettle are introduced to carry out the pre-complexation reaction and the pre-polymerization reaction of the catalyst respectively, thereby improving the isotactic index of the obtained polyolefin and maintaining the melt index at a relatively high level. high level. |
