Phase separation epoxidized triglyceride oils

Phase Separation of Two-Phase Epoxy Thermosets That Contain Epoxidized Triglyceride Oils... 

At the end of this chapter, the effect of two other epoxidized triglyceride oils—epoxidized linseed oil (ELO) and epoxidized crambe oil (ECO)—on the phase separation of DGEBA thermosets is discussed as well. 

In summary, the results show that a small variation in the nature (i.e., polarity and functionality) of the diamine or the epoxidized triglyceride oil leads to a big difference in thermoset morphology in terms of particle-size distribution (Table V) and phase inversion (Table VI). In addition to the nature of the diamines and the oils, other factors, such as their reactivity, are expected to influence the phase-separation process. Although we do not have data, a small difference in the cure rates of the DDM formulations at 75 °C and the DDS formulations at 150 °C might affect both the particle-size distribution and phase inversion.
