| titleOfInvention | Conjugated diene polymer, preparation method thereof, polybutadiene and polyisoprene |
| abstract | The invention relates to the field of conjugated diene polymer preparation, and provides a conjugated diene polymer, a preparation method thereof, polybutadiene and polyisoprene. The method is to carry out intermittent conjugated diene polymerization reaction in a single reaction kettle, wherein the conjugated diene polymerization reaction comprises a primary polymerization reaction and a secondary polymerization reaction, and the method comprises the following steps: (1) under the condition of anionic polymerization, adding a reaction material containing a first part of conjugated diene monomer, a polarity regulator, a solvent and a mono-organic lithium initiator into a reaction kettle for primary polymerization, wherein the maximum temperature of the primary polymerization is 80-110 ℃; (2) and when the highest temperature of the primary polymerization reaction is reached, adding a second part of conjugated diene monomer into the reaction kettle to carry out secondary polymerization reaction, wherein the highest temperature of the secondary polymerization reaction is 110-160 ℃. The method provided by the invention can be used for obtaining the conjugated diene polymer with wider molecular weight distribution. |
