SYNTHESIS AND CHARACTERIZATION OF A NEW THERMOTROPIC LIQUID CRYSTALLINE POLYESTER-ETHER SULFONE
摘要:
A new aromatic thermotropic liquid crystalline polyester-ether sulfone(PEES) was prepared from 4,4-bis(4-hydroxyphenoxy)diphenyl sulfone(BHPDS),terephthalic acid(TPA)and p-hydroxybenzoic acid(P-HBA).Some factors that affected melting viscosity of polymer such as prepolymerization reaction medium and post-polymerization etc,were discussed.The liquid crystalline properties were characterized by DSC,polarizing microscope with a hot stage and WAXD measurements.
