摘要
用差示扫描量热法（ＤＳＣ）研究了以对苯二甲酸双羟基乙二醇酯及其二聚体作扩链剂合成的聚醚聚氨酯酯嵌段共聚物在退火和急冷条件下的热行为，分析了材料形态和结构之间的关系。同时用动态力学分析法进一步阐述了其相容性质。
The structure property relationships of polyetherpoly (urethane ester) segmented copolymers extended by bishydroxyethyl terephthalate or its dimer were analysed by investigating their thermal responses under the conditions of annealing and quenching with DSC method Dynamic mechanical analysis method was also used to clarify the compatibility of the materials
