| Abstract: |
| The research progress on the modification of 1，2-polybutadiene by free radical addition reaction，catalytic addition reaction and olefin metathesis reaction was summarized，and the characteristics of various modification methods were analyzed.The introduction of polar functional groups into the molecule could improve 1，2-polybutadiene compatibility with polar complexing agents，processing performance，physical properties and thermal stability，and obtain special functions（such as cycleability，surface viscosity，degradability，self-healing and shape memory，etc）.The rich vinyls on molecule side chains provided many possibilities for 1，2-polybutadiene modification. |
