The purpose of this paper is to investigate the process of aminolysis of secondary polyethylene terephthalate with monoethanolamine at low ratio. The effect of the amount of monoethanolamine on the physical and chemical properties of the aminolysis product of secondary polyethylene terephthalate was studied. With an increase of 1-4 moles of monoethanolamine obtained for synthesis (without the presence of a catalyst), it was observed that the number of amines in the aminolysis product increased from 324 to 503 mgKON/g, and the number of hydroxyls increased from 298 to 491 mgKON/g. The structure of the resulting bis(2-hydroxyethylene)terephthalamide was studied using IR and thermal analysis. As a result of TGA analysis, it was found that the obtained samples have two different melting temperatures. It was shown that the incomplete reaction of IPET with MEA in a catalyst-free medium with monoethanolamine at a ratio of 2 mol, and when the ratio was increased to 4 mol, bis(2-hydroxyethylene)terephthalamide with a yield of up to 73% was obtained.
