摘要：
A new aromatic thermotropic liquid crystalline polyester-ethersulfone(PEES)was prepared from 4,4-bis(4-hydroxyphenoxy)diphenylsulfone(BHPDS),terephthalic acid(TPA)and p-hydroxybenzoic acid(P-HBA).Somefactors that affected melting viscosity of polymer such as prepolymerizationreaction medium and post-polymerization etc,were discussed.The liquidcrystalline properties were characterized by DSC,polarizing microscope witha hot stage and WAXD measurements.
