| 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. |
