摘　　要：利用含酯键的全芳和芳-脂两种复合二元酰氯分别与脂肪族和芳香族二元胺(包括氨基苯酚)合成了十余种规则芳-脂族聚酯酰胺,其中十种具有热致液晶性能。用热台偏光显微镜,DSC和X光衍射方法研究了热致液晶的相转变行为,确认了这十种聚酯酰胺均为向列型热致液晶。Two kinds of complex diacyl chlorides, wholly aromatic and aromatic-aliphatic diacyl chloride with ester bond, were used as monomers to polymerize with aliphatic and aromatic diamines respectively for preparation of regular aromatic-aliphatic polyesteramides (PEAs) . The nematic thermotropic liquid crystalline behaviour of ten kinds of PEAs obtained was studied by polarizing microscope, DSC and X-ray diffraction.
