Abstract
Chemical structures and relaxation behavior of polyacrylates synthesized using statistical and seed emulsion copolymerization methods were compared, taking into account their relaxation behavior in the glass-transition temperature range and at negative temperatures in the range from –150 to 0°C. To clarify the difference in the relaxation structures of both polymers, the effect of a water-soluble modifier on the main and local dissipative processes is considered. The relaxation microuniformity of the statistical and seed polymers is determined, taking into account also the effect of the modifier on the spectrum of internal friction of latex polymers of various polymerization structures. A theoretical approach to the assessment of the relaxation microuniformity of latex polymers is proposed based on the choice of a function for describing the dissipative processes occurring in latex polymers and its correlation with experimental data.
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.
