Abstract
Complex polyester urethanes in multicomponent solvents were used as examples for demonstrating the wide possibilities for regulating the morphology of highly-polymeric condensation structures, which were prepared with the aid of diffusional enrichment of these solutions with a nonsolvent. Dynamic light scattering was used to determine the sizes and conformation of the solution elements that determine the diversity of the resulting structures. The obtained results provided the possibility to make the conclusions about the specific features of these structures. When multicomponent solvents are used, the uncertainty of both the compositions and properties of the released phases does not yet make it possible to determine their size via this method.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
