This article investigates the aminolysis of secondary polycarbonate (IPC) (commonly found in car headlights, rims, polymer roofs, etc.) and monoethanolamine , (MEA) (GOST 10136-77 , produced in the Russian Federation) content of the main substance – 99.5%, density 1.12 g/cm 3The results of studying the aminolysis process with in the presence of a catalyst are presented. Catalyst as sodium hydroxide ( NaOH ) secondary polycarbonate ( IPC ) 1% was obtained . The main focus is on isolating urethane and phenolic compounds by performing a monoethanolamine (MEA) aminolysis process on secondary polycarbonate (IPC) and extracting the resulting product.This process was carried out in the ratio of secondary polycarbonate (IPC): monoethanolamine, (MEA) = 1:5 mol/unit . The duration of the aminolysis was carried out for a total of 6 hours at a temperature of 170 o C. The main physicochemical parameters of the resulting product and the results obtained based on infrared spectroscopy analysis are presented.
