摘　　要：对动态硫化NBR/石油发酵尼龙(PFPA)共混型热塑性弹性体的流变性能进行了研究。结果表明,NBR/PFPA为假塑性流体;表观粘度随剪切速率和剪切应力的增大而减小,随温度升高而降低;粘流活化能随PFPA用量的增大而减小。The rheological properties of dynamically vulcanized NBR/petroleum fermented polyamide(PFPA)TPE were in vestigated.The results showed that the NBR/PFPATPE was a pseudoplasticfluid, its apparent viscosity decreased with the increase of shear stress,shear rate or temperature;and the activationenergy of viscous flow decreased with theincrease of PFPA level.
