- Аннотация: The 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 00C. 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 spectra 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.
