| 摘 要： | <正> 由结晶型芳族聚酯为硬链段,无定型脂肪族聚醚为软链段的聚酯-聚醚多嵌段共聚物,是一类性能优良的热塑弹性体,本文研究链段相容性对这类聚合物组成均一性的影响,因此,合成了一系列不同链段结构的聚酯-聚醚多嵌段共聚物。 如硬链为聚对苯二甲酸乙二醇酯(PET)和丁二醇酯(PBT);软链段有聚乙二醇醚(PET)、聚丁二醇醚(PTMG)、聚二醇醚(PPG)和四氢呋喃同环氧丙烷的共聚醚二醇

| Abstract: | This paper presents a study on the effect of segment compatibility on the compositional homogeneity of polyester-polyether block copolymers. A series of such block co-polymers with various segment structures were synthesized. A transparency point determination was developed as a relative semi-quantitative comparison of segment compatibility in the melt copolyeondensation. |
