| Abstract: |
| A PVC/SBR blend was prepared through dynamic vulcanization. The influence of rubber/plastics ratio，curing system，compatibilizer and PVC crosslink on the properties of blend was investigated. The results showed that the optimum comprehensive properties of the blend were obtained when the PVC/SBR（75/25） blend，the NBR/CPE（2.5/2.5）compatibilizer，the semi-EV system or semi-EV system+ 2phr of DCP were used. The compression set could be significantly improved when 0.4 phr of accelerator NA-22 was added to PVC. |
