The effect of polyetherimide on the viscosity and physicomechanical characteristics of epoxides was investigated. It is shown that the introduction of polyetherimide increases the viscosity of the ED-20 oligomer and enables one to increase the crack resistance of cured resin four times, its impact resistance 1.5 times, and the total impact energy two times. The improvement in these properties is related to structural changes of the composition with increasing concentration of the thermoplastic.
