Experimental data are shown which confirm the existence of increased macromolecules association in a polymer mixture. The increase of association is revealed in the increase of light scattering intensity and the increase of density (local ordering increase). The grown up association degree determines the peculiarities of network formation through cross‐links in the solution of polymer mixtures. Macromolecules associates degrade under mechanical stresses or after addition of slight amounts of substances which are able to interact intensively intermolecularly (solvating) with macromolecules of one of the polymer components in the mixture. Representation of associates formation and degradation in polymer mixture help to explain many experimental data on thermodynamics, structure and properties of polymer mixtures.
