摘　　要：本文报导了使用HAAKE转矩流变仪,AG—10TA万能材料试验机对特种工程塑料聚醚砜（PES）流变性能的研究。研究结果表明:国产PES为典型的假塑性流体,非牛顿指数n=0.33～0.63,粘流活化能E=30.7～70.7kJ/mol,比VictrexTMPES的小。PES在成型时机器负荷不会太大,但物料在机器中停留时间不宜太长。在PES的加工过程中会出现熔体增稠现象。The rheological property of PES was investigated by making use of HAAKE torque rheometer and AG—10TA universal testing machine. The knowlodge of the theological behaviour of PES over an industrially relevant range of shear rate and temperature is essential for the assessment of the material processibility, process design/optimization and troubleshooting. A thickering of melt during processing of PES was found by the author.
