A class of star compound containing cyclopentadiene and its preparation method |
| abstract |
The invention relates to a class of cyclopentadiene-containing star compounds and a preparation method thereof. A class of cyclopentadiene-containing star compounds is prepared by reacting cyclopentadiene and its derivatives with star halides under the action of inorganic bases. The preparation method of a cyclopentadiene-containing star compound disclosed by the present invention has simple synthesis process, high yield, easy-to-obtain raw materials and mild reaction conditions. A star compound containing cyclopentadiene disclosed by the present invention can be used as a branching agent to prepare a star-shaped rare-earth catalyst in the preparation reaction of a rare-earth catalyst for the polymerization of a conjugated diene, thereby preparing a star-shaped branched polymer. Reduce polymer solution viscosity. |
