| 摘 要： | 本文用常压合成方法制备了中央嵌段为39个环氧乙烷单位的环氧丙烷-环氧乙烷-环氧丙垸三嵌段共聚醚P_xE_(3(?))P_x系列;用凝胶渗透色谱法(HPGPC)与质子核磁共振法(′HNMR)表征系列的嵌段组成;用小角X射线衍射(SAXD)、低频拉曼光谱、差示扫描量热法(DSC)研究了系列的固态结构形态。研究表明:固态的P_xE_(3(?))P_x共聚醚系列由单层晶片堆集而成,非折迭的分子鏈在片中的取向一般是傾斜于片的端面。

| Abstract: | Abstract A Series of block copolyether with the structure of propylene oxideethylene oxide-propylene oxide in which the middle block has 39 repeated ethyleae oxide units were made by a polymerization at ordinary pressure. The block compositions of the series have been characterized by gel permeation chromato-graphy (GPC) and proton nuclear magnetic resonance ('HNMR). The solid structure state of the series has been studied by using small angle X-ray diffraction (SAXD), low frequency Raman spectroscopy and differential scanning calorimetry (DSC). The results show that the series of copolyether of P_xE_(39)P_x in solid state is made up by stacking single crystal layer pieces. The orientation of the non-folded molecular chains in the layer tilts towards the end surface of the layer. |
