| titleOfInvention | Polyisoprene and preparation method thereof |
| abstract | The present invention relates to the technical field of synthetic rubber, in particular, to polyisoprene and a preparation method thereof. The method includes mixing isoprene as a monomer in an organic solvent in the presence of a rare earth catalyst as a homogeneous solution containing component A, component B, component C, component D and component E Carry out a polymerization reaction; component A: neodymium phosphonate compound represented by formula (1); component B: alkyl aluminum compound; component C: halogenated compound; component D: CH 2 =C(R 2 )-CH=CH 2 ; component E: a compound represented by formula (2). The preparation method provided by the invention has the advantage of low catalyst consumption, can obtain polyisoprene under the condition that the neodymium/monomer molar ratio is below 8.5×10 5 , and the catalyst consumption is 200mgNd/kgPI. |
