OF THE RHEOLOGICAL BEHAVIOR OF OLIGOMER SYSTEMS

The distinctive features of the rheological behavior of oligomer 
liquids have been considered within the framework of the concept of 
the aggregative nature of their supermolecular structure. It has been 
shown that the dependence of the rheological properties of oligomers 
on the temperature-time and deformation prehistory is a consequence 
of the system's nonequilibrium at the instant of measurement. Theoretical 
models quantitatively describing the evolution of the system to thermodynamic 
equilibrium have been proposed. Account for the kinetics of formation 
of the supermolecular structure of oligomer liquids enables one to 
correctly explain certain experimental "anomalies," thus transferring 
them to the class of fundamental physicochemical regularities.
