Аннотация: Plant biomass, in particular forestry wastes, is a promising renewable feedstock for deep chemical processing. Organosolv methods allow the use of underutilized lignin. The synthesis of modified polymers by azo coupling with the use of aspen (Populus tremula) ethanol lignin and its sulfated modification is studied. The success of the synthesis has been proven and the features of the structure and properties of the synthesized samples were studied by the physicochemical techniques, including Fourier transform infrared and nuclear magnetic resonance spectroscopy, gel permeation chromatography and thermogravimetric analysis. It was shown that the new azopolymers have the ability to photoisomerize, which opens up prospects for their high-tech applications. The modified lignins are proven to be bioactive antioxidants.
