Miscibility of epoxy resins/poly(ethylene oxide) blends cured with phthalic anhydride

Epoxy resin containing poly(ethylene oxide)-block-poly(ɛ-caprolactone) diblock copolymer: Effect of curing agents on nanostructures

“…It was ever reported that phase separation occurred in the blends of epoxy resin with PEO when the blends were cured with tetraethylenepentamine, an aliphatic amine [23]. Nonetheless, subsequent studies showed that the system is miscible when cured with aromatic amines [24]. For the blends of epoxy with PCL, miscibility and phase behavior have been reported by several authors [25e34].…”

Thermophysical Properties and Molecular Relaxations in Cured Epoxy Resin + PEO Blends: Observations on Factors Controlling Miscibility

“…[18][19][20][21][22] The T g -composition relationship observed in our blends (Table 1 and Figure 3) has been described in the left half of the diagram by an empirical equation of Kwei [35] T blend…”

Dielectric properties of cured epoxy resin+poly(ethylene oxide) blends

“…However, polyether-type polymers, such as polyacetal (polyoxymethylene), poly(2,6-dimethyl-1,4-phenylene oxide) [8] and poly(ether imide) [9] have been incorporated with crosslinking ERs yielding phase-separated morphology. Immiscibility has also been reported for DGEBA + PEO blends cured with aliphatic amines [5,10], but not in the case where aromatic amines [5,[11][12][13] or anhydrites [5,14] were used. The influence of potential strong dH interactions on the growth rate and spherulite morphology of PEO in miscible blends has been well established, but their potential contribution on miscibility has been questioned [5].…”
