摘要：

The synthesis and the partial characterization of the phase behaviour of a homologous set of polymers of 4,4'-[1,12-dodecanediylbis(oxy)]bis(benzoic acid) with bis[N-[[2,4-dihydroxyphenyl]methylene]-alkylamino]copper(II) is reported. Polymers that differ by the number n (4-13) of carbon atoms in the alkylamino groups exhibit monotropic liquid-crystalline behavior. Calorimeter analysis, polarizing microscopy, and dynamic viscosity measurements indicate the occurrence of nematic mesomorphism for all polymers. With n > 9, an additional mesophase of presumably smectic structure forms on cooling the molten polymer and is detectable at room temperature by X-ray diffraction.
