Tri-functional vanillin-derived epoxy monomer (GDVCPO) was developed through the synthesized di-functional reagent (GDVCP) via oximation and cured with a same type of hardener (amine based) to evaluate thermal properties of the resultant epoxy thermosets [1]. At 30 oC, the polymers were all glassy and the progress of curing process was followed by evaluation of the most significant band in FT-IR and DSC thermogram. The number of monomer functionality was found to develop thermal properties of the resultant products to higher value [2] (from 97 to 140 oC). According to the obtained results, increasing the number of functional groups in monomer, increased the cross-linking density and Tg [3] of EDVCPO-DDN comparing with EDVCP-DDN network (140 oC and 97 oC, respectively).
