Specific features of polymer modification based on complexation between low-molecular-mass modifying agents and polymers were discussed in terms of structural inhomogeneity of amorphous glassy polymers. Complexation between low-molecular-mass compounds (LMs) and polymer macrochains in structural regions with different packing densities was shown to be responsible for the distribution of LMs between two forms, which are characterized by different energetics of interaction with polymer matrix. The occurrence of such distribution was controlled by chemical structure of LM molecules and local packing of polymer macrochains. This distribution was responsible for a complicated character of molecular dynamics in the polymer/LM systems and mechanical behavior of such materials in whole. The cases, when macroscopic mechanical behavior of as-modified polymers was primarily controlled by the form, in which the modifying agent existed in polymer matrix, were considered. The future development of this direction of polymer modification was discussed and possibilities of its practical application for controlled improvement in mechanical response of polymer materials were outlined. |
