INFLUENCE OF THERMOPLASTIC MODIFIERS ON THE PROPERTIES AND THE PROCESS OF CURING OF EPOXY POLYMERSI. Yu. Gorbunova, N. V. Shustov, and M. L. Kerber UDC 541.64:532.125 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. D. I.
