| titleOfInvention |
A kind of constrained configuration double metal compound and its preparation method and application |
| abstract |
The invention discloses a restricted configuration bimetallic compound as well as a preparation method and application thereof. The compound has a double center, not only has the activity of a single-site catalyst, but also conveniently controls the electronic environment and space environment of the two metal centers by adjusting the substituent, and then regulates the molecular weight distribution of the polymer to produce high-molecular-weight, wide-ranging Distributes polyolefins and is used in the preparation of ethylene/1‑octene copolymers. The preparation method of the invention has the advantages of short synthesis route, simple synthesis process and low industrial cost. |
