STUDIES ON THE SEQUENCE STRUCTURE OF TPA/EG/PHB LIQUID CRYSTALLINE COPOLYESTERS
the sequence structure of TPA/EG/PHB liquid crystalline copolyesters made from different synthetic methods has been studied by
1
H-NMR with the help of computer program of processing peaks. The results showed that the ether bonds were not observed in TPA./EG/PHB copolyesters and the synthetic process had a great effect on their sequence structure. Under certain conditions
the high
random TPA/EG/PHB copolyesters which were considered to have higher performances than PET/xPHB could be obtained.
