Abstract
New polyazomethines were synthesized by low-temperature polycondensation of urea and aromatic dialdehydes. The optimal conditions for the process of obtaining polyazomethines have been determined. The structure of the obtained polyazomethines was determined by IR spectroscopy and elemental analysis methods. The synthesized polyazomethines are partially crystalline, highly soluble and fusible materials. It was established that the synthesized polyazomethines have an increased thermal stability, which depends on the structure of the initial aromatic dialdehyde. It was found that polyazomethine based on carbamide and 4,4’-diform yldiphenoxyterephthalate melts, exhibiting liquid crystalline properties. It was shown that the obtained polyazomethines are fiber and film-forming materials.
