| Abstract: |
| The CIIR/polydodecalactam 12(PA12) thermoplastic vulcanizate（TPV） was prepared by dynamic vulcanization，the influence of blend ratio，the addition level of curing agent，the compatibilizer species and dynamic vulcanization process on the physical properties，rheological behaviour and air permeability of CIIR/PA12 TPV were investigated.The results showed that as the blend ratio of CIIR/PA12 was 65/35～60/40，the addition level of curing agent HVA-2 was 2 phr，5 phr maleic anhydride graft polypropylene was added，and twin-screw extruder was used for dynamic vulcanization，CIIR/PA12 TPV gained better physical properties，rheological behaviour and air permeability performance. |
