摘　　要：考查了聚醚酮酮溶于浓硫酸中的时间与特性粘度的关系,探讨了通过不同特性粘度聚醚酮酮的共混来调节共混物特性粘度的方法。比较了用浓硫酸为溶剂时,采用单点法、外推法和算图法测定聚醚酮酮特性粘度时的优、缺点.结果认为算图法是一种快速、较准确的测定特性粘度的方法。The effect of duration of polyetherketoneketone dissolved in concentrated sulfuric acid on its intrinsic viscosity by blending several series of polyetherketoneketone with different molecular weight was investigated. Compared to solomon - ciuta method and extrapalation, homographic method was a quicker and accurate method to obtain intrinsic viscosity of polyetherketoneketone.
