The basic features of the rheokinetic behavior of an epoxy 
oligomer cured by 4,4-diaminodiphenylsulfone have been determined. 
It has been established that the process of curing obeys the phenomenological 
equation of first order with self-acceleration. Different modifiers 
based on linear thermally resistant polymers have been employed to 
improve the physicochemical properties of the compositions. Making 
such additions enabled us to increase the thermal resistance of materials 
and the resistance to impact loads.
