| 中文摘要 | new poly(azomethine sulfones) with linear structures containing sulfonyl bis(4-phenoxyphenylene) and oxo bis(benzylideneaniline) or methylene bis(benzylideneaniline) units were prepared in the conventional literature manner by condensing the dialdehyde sulfone monomer (v) with diamines such as 4,4'-oxydianiline (iiia) and 4,4'-methylenedianiline (iiib), or by condensing an azomethine biphenol (ix) with 4,4'-sulfonyldichlorobenzene (ii). three model compounds which reproduced the above structures were also synthesized. the resulting polymers were confirmed by ir, h-1-nmp, and elemental analysis, and were characterized by inherent viscosities, thermogravimetric analysis (tga), and x-ray diffraction. the thermotropic liquid crystalline (tlc) behavior was studied using polarization light microscopy (plm), thermooptical analysis (toa), and dsc. a nematic texture was observed only for 4,4'-oxydianiline-units-based polymers. the reaction of polymer viiib containing -ch2- links between the mesogens with the model compound ix led to polymer x which exhibited tlc behavior. |
