The physicochemical differences in the modifying action of mono- and dilaproxides on the process of the structure formation of cured epoxy oligomers were established. The physically well-founded standard temperatures of epoxy–laproxide composites of different composition were established by differentiation. The results of investigating the high elasticity, the inversion features, and the deformation and strength properties of these densely crosslinked polymers are given. It is shown that the use of difunctional laproxide L-702 as a modifier of ED-16 and ED-20 resins is preferable to the use of monofunctional oligoether epoxide L-301.
