%X 采用动态硫化方法制备CIIR/聚十二内酰胺(PA12)热塑性硫化胶(TPV)，研究增塑剂环烷油、聚异丁烯和N-丁基苯磺酰胺对CIIR/PA12 TPV物理性能、流变性能、结晶性能、动态力学性能和气密性的影响。结果表明：N-丁基苯磺酰胺对CIIR/PA12 TPV有一定的增塑效果；与环烷油和聚异丁烯相比，N-丁基苯磺酰胺用量较小时，在保持物理性能和气密性基本不变的前提下，显著减小了TPV硬度，并改善了挤出物外观形貌和加工性能；加入N-丁基苯磺酰胺后，在不影响塑料相结晶性的前提下，PA12的玻璃化温度最大下降了40 ℃左右。;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 ℃
