本文通过熔融指数（ＭＩ）和流变性能的研究，表明聚醚醚酮酮为典型的假塑性流体，流动行为指数ｎ＝０．６３～０．６７，粘流活化能为７５ｋＪ／ｍｏｌ，比聚醚醚酮高２０～３０ｋＪ／ｍｏｌ。
In this paper, the melt index (MI) and rheological properties of the study showed that the polyetheretherketone ketone is a typical pseudoplastic fluid, the flow behavior index n = 0.63 ~ 0.67, viscous flow activation energy of 75kJ / mol, than Polyether ether ketone high 20 ~ 30kJ / mol.
