The work is devoted to the investigation of the viscous properties of a nanostructured additive based on sevilene, as well as the evaluation of its structure by the method of IR Fourier spectroscopy on the Shimadzu IR Prestige-21 Fourier spectrometer. The structure of agglomerates of the additive is proposed, which consists of a core-nano-sized particle of aluminum oxide bound to polymers (sevilene) by associative bonds. In this case, a partial restructuring of vinyl acetate units occurs. The absorption band of 13...
