| titleOfInvention | Composition for rare earth catalyst, preparation method and application thereof, and olefin polymerization method |
| abstract | The invention provides a composition for a rare earth catalyst, wherein the composition comprises: a) a neodymium compound; b) a halide; c) an alkyl aluminum compound; d) a hydroxyl and/or carboxyl group-containing C6-C18 organic compound; e) and (3) water. The invention provides a rare earth catalyst and a preparation method thereof. The invention provides a rare earth catalyst prepared by the preparation method of the rare earth catalyst. The invention provides an application of the catalyst in conjugated diene polymerization. The present invention provides an olefin polymerization process comprising: under the condition of olefin polymerization, conjugated diene is contacted with a rare earth catalyst, wherein the rare earth catalyst is the rare earth catalyst provided by the invention. The neodymium rare earth catalyst has high activity and high catalyst efficiency, and can effectively reduce the production cost. |
