The most relevant aspect of this self-organization is the relationship between structure and properties in dispersed systems, which largely determines the properties of future polymer composites. One of the most common dispersed media is diene oligomers (rubbers). This work examined the rheology of oligobutadienes with terminal hydroxyl (HTPB) and carboxyl (HTPB_m1) groups over a wide range of shear rates and temperatures. It was assumed that, for the studied oligobutadienes, the increase in the activation energy of viscous flow (from 33.5 to 66.4 kJ\/mol) with decreasing temperature is associated with an increase in the density of the fluctuating dynamic structure with an increase in the volume content of polar OH- and COOH-group associates (i.e., non-ionic micelles) with a decrease in thermal energy kT (k is the Boltzmann constant). The results of rheological studies (for non-ionic liquids) were presented for the first time within the framework of Angel&#8217;s model, which indicated that these systems are fragile, i.e., they are very promising for studying structure formation in a shear field.<\/p>\n<p><strong>Keywords<\/strong>: rheology, viscosity, shear deformation, self-organization, activation energy, Angel&#8217;s model<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h4><strong>REFERENCES<\/strong><\/h4>\n<p>Shumsky V.F., Boiko V.P., Getmanchuk I.P., Grishchenko V.K., Nistratov A.V., Novakov I.A.
