摘　　要：采用ARES-RFS流变仪研究了低温缩聚法制备含氮杂环均聚芳香族聚酰胺纺丝溶液的流变特性,讨论了聚合物的质量分数、相对分子质量、温度对纺丝溶液流变特性的影响.结果表明:含氮杂环均聚芳香族聚酰胺溶液为切力变稀的非牛顿流体;溶液的非牛顿指数随溶液中聚合物质量分数和相对分子质量的增加而减小,随温度的升高而增加,但聚合物质量分数在三者中的影响作用尤为显著;纺丝溶液的结构化指数随影响因素变化的范围较大.The rheological behaviors of heterocyclic aromatic polyamide spinning solutions made by low temperature polymerization were studied by using ARES-RFS rheometer. The effects of heterocyclic aromatic polyamide spinning solution concentration, relative molecular weight and temperature on theological behaviors were discussed, respectively. The results indicated that heterocyclic aromatic polyamide spinning solution was a typical non-Newtonian fluid. The non-Newtonian index of the solution decreased with the increasing of solution concentration and the relative molecular weight, but increased with the temperature elevating. The effect of solution concentration compared to the other two factors, was most obvious. The structure viscosity index varied a lot with the changes of influencing factors.
