摘要：

The effect was investigated of carbon black, added to the reaction mixture of a segmented polyester urethane based on oligooxytetramethylene glycol, 4,4**1-diphenylmethane diisocyanate, and 1,4-butanediol, on its structure and complex properties. It was found that addition of filler in the process of PEU synthesis leads to a significant change in its properties by virtue of the fact that the presence of an interface with the solid in the polymer-formation process causes structural disturbances, displayed in loosening of rigid domains, playing the role of nodes of a physical grid in segmented polyurethanes, together with a decrease in molecular mass of the system.
