| Abstract: |
| In this work, the brominated isobutylene isoprene rubber (BIIR) was prepared through solvent free bromination process using regular rubber processing equipment in which IIR was modified using pre-dispersed compound containing N-bromosuccinimide, small amount of IIR and stabilizer.The structure of product was characterized by FTIR and 1H-NMR spectra，and the effect of reaction conditions（time，temperature and bromination agent level）on the curing characteristics and mechanical properties of BIIR was investigated.It was found that there was no equipment corrosion using this process.Compared with IIR，the curing rate of prepared BIIR increased significantly，and the curing characteristics and mechanical properties of the product reached the level of the commercial BIIR.The brominating reaction temperature should be at 60～100 ℃，and the addition level of brominating agent and the brominating time had little effect on the curing characteristics and mechanical properties of BIIR. |
