【摘要】 聚芳醚矾(PES)无广角X-射线的结晶衍射,但其本体及溶液均具有解偏振效应。其形态结构单元是由棒状分子规整排列形成的微区。微区进一步堆砌排列形成棒状的亚微观结构。由于链结构不同,其大分子链的刚性不同,导致形态结构尺寸与堆砌花样有所不同。这些形态结构随外界条件变化而改变。

【Abstract】 There is no crystalline diffraction of wide-Angle X-ray to be discovered in PES, but there is birefringence effect both in its bulk and solution. Its morphological structure unit is a rodlike macromolecule which drrdnges regularly to form domdins, then these domains pack further to form a rodlike submicroscopic structure. The different chain rigidities are due to the different chain structures which induce different dimensions of morphological structure and packing patterns. These morphological structures change with external conditions. All of the above characteristic structures form an important basis for the study of the meso-phase of PES.
