摘　　要：采用锥板流变仪,研究了含杂环共聚芳香族聚酰胺溶液的动态流变特性。结果表明:含杂环共聚芳香族聚酰胺溶液为假塑性流体;溶液浓度越高,相对分子质量越大,其储能模量(G′)和损耗模量(G″)越大,但G′和G″随温度的升高而降低;随着含杂环共聚芳香族聚酰胺相对分子质量的增大,其相对分子质量分布越宽,溶液中大分子缠结网增强。The dynamic rheological behavior of heterocyclic aromatic co-polyamide solution was studied with a cone-and-plate rheometer. The results showed that the heterocyclic aromatic co-polyamide solution belonged to pseudoplastic fluid; the higher the concentration and the relative molecular mass of the solution were, the higher the storage modulus （G＇） and loss modulus （ G＂ ） were ; but G＇ and G＂ dropped with the temperature elevation ; and the macromolecular entanglement network in the solution was enhanced as the relative molecular mass and its distribution of heterocyclic aromatic polyamide solution were increased.
