Annotation	This work reports the results of a study of the microstructural and dynamical properties of self-assembled triblock copolymers. It was performed using adiabatic calorimetry, ultrasonic spectroscopy and dynamic light scattering. In the vicinity of supramolecular transitions, first aggregates occur; with further increasing temperature a spontaneous forming of compact structures was observed in the system. These results are supported by data of the shear viscosity and free internal volume parameters calculated in the framework of the Frenkel-Andrade approach.
