Abstract

The fractal characteristics of individual macromolecular tangles of block and random copolymers are investigated. It was found that the dependence of the mass of macromolecules on the radius of inertia of a statistically significant sample is well described by the de Gennes equation with a fractal dimension of 5/3. It was established that the fine structure of the polymer coil also has a fractal nature. The fractal dimension inside the macromolecular coil changes significantly with distance from the center of mass.
