NMR对聚酯-聚酯多嵌段共聚合物的研究
STUDY OF THE POLYESTER-POLYESTER MULTIBLOCK COPOLYMERS BY ~1H-NMR
【摘要】 本文用~1H-NMR研究了硬段含量不同的一个系列的PET-PCL多嵌段共聚合物,利用多种信息和技术对谱峰进行了归属,从而获得了用~1H-NMR描述这种多嵌段共聚合物的数学表达式,确定了它们的分子链结机,并解得了各结构单元之间的数量关系。
【Abstract】 A series of PET PCL polyester - polyester multiblock copolymers with different weight ratio of the hard to the soft segments have been studied by 1H-NMR. peaks were assigned by using various spectral informations and techniques.Thus, mathematical expressions which decribe well the multiblock copolymers with 1H-NMR. sequence structure of the chemical chains and quantitative relations in each structure units were obtained.
