Дослідження гумінових кислот та речовин, як гібридних модифікаторів полімерів

Abstract

The study of humic acids and substances as hybrid modifiers of polymers is carried out in the work. The method of IR analysis was used to determine the most characteristic functional groups in humic acids derived from brown coal. Among the most characteristic spectral bands of humic acids should be noted: phenolic −OH hydroxyl groups at 3380-3400 cm⁻¹, aliphatic bands C–H at 2920-2940 cm⁻¹, symmetric νCOO– carboxyl and νCO (phenolic), νOH (aliphatic) at 1100cm⁻¹. It has been established that the presence of these functional groups determines the ability of humic acids to act as a hybrid modifier in relation to polymers.
