| Abstract: |
| Two kinds of domestic low cis polybutadiene rubber（BR） were used to replace imported high cis BR to prepare high impact polystyrene（HIPS） HIE-1．The results showed that the optimum dosage ratio of low cis BR 50AF and BR P30AF was 30/28．When the particle size of rubber phase was 3.5 μm and the weight average molecular weight of HIPS was 2.65×105 ～ 2.70×105，the toughening effect of low cis BR on HIPS was the best．The HIPS products had excellent impact resistance and reduced cost compared with the one with imported expensive high cis BR. With key technical transformation, the process problems were solved and mass production of HIPS was achieved. |
