Abstract

For numerical treatment of resin‐containing systems and forecasting of their properties, certain models of branching are needed. In this review, existing theoretical models of systems containing branched structures (polymers, aggregates, etc.) are analyzed and compared. The criteria of selection of the optimal theoretical model comprise chemical and physical problems available for solution, simplicity of such solution, connection between theoretically forecasted and experimental results, and the time needed for computing. It is concluded that, according to these criteria, the optimal (between existing models) is the statistical polymer method.

Abstract

The problem of the analytical modeling of macromolecular systems with branching is solved by the statistical polymer, which is based on consideration of averaged structures. All interactions are described in terms of statistical polymers. Cross‐linking is considered as a result of interactions inside statistical polymers. It is concluded that cross‐linking may result in the formation of infinitely hard structures and gelling. Thermodynamic functions of statistical polymers are derived and employed for simulation of the evolution of a non‐equilibrium polymeric system. Equations for the evaluation of various parameters of polymeric systems with branching are derived. Theoretical results are used for the preparation of new materials (having a branched, cross‐linked structure) with forecasted properties.

Abstract

This study considers the problem of preventing the penetration of corrosion‐active components into the protective coating of various materials. It is shown that inhibitors involved into micropores and various coating defects seriously reduce the rate of penetration. The mass‐transfer aspects of the inhibition of acid diffusion into coatings were analyzed. It is shown that the effectiveness of inhibition cannot be easily related to the chemical composition of inhibitors.
