| Abstract: |
| Using IIR，hydrogen bromide and hydrogen peroxide solution as raw materials，and using chloroform as solvent，bromobutyl rubber（BIIR）was prepared by orthogonal experiment design.The influence of the temperature and time of reaction，glue concentration and initiator on the bromine content of BIIR were investigated，and its cure characteristics were investigated.The results showed that，the optimum reaction conditions were as follows:temperature 50 ℃，reaction time 5 min， glue mass fraction 0.15.The unsaturation value of BIIR decreased，the molecular weight rose 20%，the molecular weight distribution was broadened，and curing rate increased by about 30% compared with IIR. |
