热致液晶共聚酯／含酚酞侧基聚芳醚砜共混物的流变行为研究

Study on the Rhelolgical Properties of LCP/PES-C Blends

摘要: 采用溶液共混制备耻不同比例的热致液晶共聚酯／含酚酞侧基聚芳醚砜共混物。利用锥板流变仪对共混体系的熔体流变性能进行了初步研究，测定了熔体粘度－温度、粘度－剪切速度的关系，结果表明该液晶聚合物能明显降低聚芳醚砜的熔体粘度。

Abstract: Different content, blends of phenolphthalein polyarylether sulfone (PES-C) with thermotropic liquid crystalline copolyester (LCP) were prepared by cop-recipitation. The rheological behavior of the blends were studied by cone plate rheometer. The relations
