The molecular properties of diluted solutions of Pepper’s lignin from the stems of Serratula coronata L. saw-wort in dimethylformamide are studied by capillary viscometry and sedimentation-diffusion analysis. The MMs of fractions and the hydrodynamic radii of macromolecules are determined, and the scaling dependences are analyzed within the framework of the Mark–Kuhn–Houwink equation. It is shown...
The topological structure of macromolecules of Pepper lignin isolated from bamboo stems is studied. The molecular properties of dilute lignin solutions in dimethylformamide are investigated by the methods of high-velocity sedimentation, translational diffusion, and viscometry. The molecular mass of fractions, the scaling coefficients of the Kuhn–Mark–Houwink equation, and the Tsvetkov–Klenin hydrodynamic...
