Abstract
Abstract In the article are discussed the relevance of obtaining amino aldehyde oligomers and the study of their basic physicochemical properties and determines that the synthesis conditions and the ratio of the starting components play an important role on the properties and structure of the synthesized amino aldehyde oligomers. Using the Differential thermal analysis (DTA) method, it was proved that the modification of the urea-formaldehyde oligomer with acrylic acid helps to increase the thermal oxidative degradation of the resulting products. In this case, the modifier - acrylic acid strongly chemically binds with amino aldehyde oligomers, which leads to an increase in the heat resistance of the samples.
