| titleOfInvention | Method for synthesizing high cis-diene polymer |
| abstract | The invention provides a method for synthesizing a high cis-diene polymer, which comprises the following steps: in an anhydrous and oxygen-free closed container, carrying out polymerization reaction on a reaction solution containing a diene monomer, liquid pentane and a rare earth composite catalyst to obtain a high cis-diene polymer; the diene monomer is liquid butadiene and/or isoprene; the filling degree of the reaction solution in the closed container is 30-70%. According to the invention, liquid butadiene and/or isoprene is used as a raw material, pentane with a low boiling point is used as a solvent, and polymerization is carried out under the catalysis of the rare earth composite catalyst under the anhydrous and oxygen-free closed conditions, after the reaction is finished, pentane can be volatilized at room temperature, so that the solvent residue in the product is reduced, the obtained product is easy to recover and separate, the post-treatment temperature of the product is reduced, and energy is saved. |
