Radial-density distribution functions of segments and radii of gyration are obtained for the first time with the example of systems of statistical butadiene–styrene rubber of different composition and polystyrene by the processing of electron-microscopy images of individual copolymer molecules. Linear correlation dependences of R = f(M 1/2) are plotted. The possibility of quantitative determination of fluctuation deviation from the equilibrium radius value is demonstrated. A method of calculating the values of Flory–Huggins parameters for individual macromolecules and their assembly is suggested.
