中文摘要: 用自制的3-氨基-4-羟基苯甲酸盐酸盐（ABBAH）在多聚磷酸（PPA）中合成聚（2,5-苯并噁唑）（ABPBO），利用衰减全反射红外光谱（ATR-IR)表征了其化学结构。分别用平板流变仪和毛细管流变仪对合成的ABPBO PPA溶液进行动态和稳态流变测试。结果表明： ABPBO-PPA溶液的储能模量（G′）和损耗模量（G″）均随频率升高而增大，且储能模量比损耗模量上升得更快；ABPBO-PPA溶液随温度升高趋于牛顿流体，随浓度升高非牛顿性更显著,ABPBO-PPA溶液表现出强烈的假塑性，并且不同温度下溶液的剪切黏度差值随剪切应力增大而减小。
Abstract:Poly(2,5-benzoxazole) (ABPBO) was synthesized from 3-amino-4-hydroxybenzoic acid hydrochloride made by solution polycondensation in the solvent of polyphosphoric acid (PPA). Chemical structure of the polymer was tested with ATR-IR. Then the dynamic rheological behavior of ABPBO PPA solution was tested with a parallel plate rheometer, and the steady flow curve was tested with a capillary rheometer. Results showed that the storage and loss modulus increased as frequency increased, and storage modulus increased more quickly than the loss modulus. ABPBO-PPA solution tended to Newtonian fluid with the temperature rising. However, it tended to non Newtonian fluid with the increasing of the ABPBO-PPA concentration. ABPBO-PPA solution behaved sharp pseudoplastic. And the disparity of viscosities with different temperatures decreased with the shear stress increasing.
