摘　　要：应用平行板流变仪，研究了尼龙1212（PA1212）／[苯乙烯／（乙烯／丁烯）／苯乙烯]嵌段共聚物接枝马来酸酐（SEBS-g-MAH）／邻苯二甲酸二异癸酯（DIDP）／N-丁基苯磺酰胺（BSBA）共混物熔体在230℃下的动态粘弹特性。结果表明，在剪切速率0．1-100s^-1范围内，共混物熔体的剪切储能模量和剪切损耗模量均随着剪切速率的增加而呈非线性函数形式增大；动态复合粘度则随着剪切速率的增加而呈近似幂律函数形式减小。当在低剪切速率下．动态复合粘度随着SEBS-g-MAH含量的增加而显著增大。The dynamic-viscoelastic properties of nylon 1212/SEBS-g-MAH/DIDP/BSBA blends at 230℃ were investigated by means of parallel-plate rheometer. The results showed that the storage modulus and loss modulus both increased with the increase of shear rate in the range of 0.1 - 100s^-1 in the form of nonlinear function. The complex viscosity decreased with the increase of shear rate in the form of approximate power law function. The complex viscosity increased greatly with the increase of the SEBS-g-MAH content at low shear rate.
