| Abstract: |
| The CIIR/polydodecalactam 12(PA12) thermoplastic vulcanizate(TPV) was prepared by dynamic vulcanization，the influence of naphthenic oil，polyisobutylene and N-butyl benzenesulfonamide on the physical properties，rheological behavior，crystallization，dynamic mechanical properties and air permeability of CIIR/PA12 TPV was investigated.The results showed that N-butyl benzenesulfonamide was effective plastizer of CIIR/PA12 TPV.Compared to naphthenic oil and polyisobutylene，with small amount of N-butyl benzenesulfonamide，the physical properties and air permeability of TPV changed a little,but the hardness was reduced significantly,and the extrudate appearance and processing property were improved.N-butyl benzenesulfonamide had little effect on the crystallization of plastic phase，and the glass transition temperature of PA12 decreased up to 40 ℃. |
