Studies on the phase separation of polyetherimide-modified epoxy resin, 3. Morphology development of the blend during curing

A novel benzoxazine/bismaleimide blend resulting in bi-continuous phase separated morphology

“…[2][3][4][5] Compared with the rubber/TS system, the TP/TS system has drawn more attention because of the improved toughness with less loss of thermal and modulus properties. Inoue, [6][7][8] Pascault [9][10][11] and Shanjun Li [12][13][14][15][16][17] have prepared resins by blending thermosets with high-performance thermoplastics such as polyaromatic ether sulfone and polyether imide. The blends shows improved toughness at the expense of heat-resistance, high mechanical strength and modulus with the formation of bi-continuous and phase inverted structure (the dispersed phase is thermoset and the continuous phase is thermoplastic).…”

Studies on novel composites of polyoxymethylene/ polyamide 6

“…On the other hand, in situ polymerization technique is another effective way to control morphologies of polymer blends, mainly from the angle of kinetics of phase separation. As for this method, much attention has been paid to rubber or thermoplastic‐modified thermosetting polymer systems, such as epoxy resins/thermoplastic systems 4–12. As reported, such types of morphologies can be controlled by the dissolution/diffusion of thermoplastic in reactive solvent and the thermodynamics combined with the kinetics of reaction of the systems 13…”
