Essay

The thesis is devoted to investigation of structure, morphology, dielectric relaxation and ionic conductivity of polyurethanes (PUs) that characterized by a presence of carboxylic or Li-, Na, K-carboxylate groups in the flexible poly(tetramethylene glycol) based segments. The PUs involved develop, in line with a presence of the structure, that is typical for conventional segmented PUs, ionic aggregation. The formation of the ionic aggregation structure is followed by decreasing a level of ionic conductivity.
