The cured epoxy resin systems which are modified by the statistical monofunctional reactive polymers have physical properties, such as adhesion and elongation, generally equal to or better than those of cured epoxy resin systems modified with statistical difunctional reactive polymers. A process of preparation for the modified epoxy resin systems of the present invention includes admixing an epoxy resin with a statistical monofunctional carboxyl, amine, or epoxy terminated reactive polymer in the presence of a curing agent and reaction therewith to form the toughened, cured epoxy resin system.
