• BioBased Aromatic Epoxy Monomers for Thermoset Materials

    Jan 17, 2017· Recently Liu et al. developed a sixarmed epoxy resin (23) based on linoleic acid and hexamethylol melamine in a twostep process of esterification and epoxidation with H 2 O 2 (Figure 18). Their goal was to reduce the high flexibility induced by the long aliphatic chain of the vegetable oils by introducing a rigid aromatic group.
