Particularly, the copolymers with ESO Contents from 40 to 80%' underwent phase separation when curing under the conditions used herein, due to differences in DGEBA and ESO reactivity with MTHPA.

Since the use of MTHPA with Cloisite 30B organo-clay nanoplatelets resulted in better exfoliation and larger expansion of intercalated clay nanoplatelets when compared with the use of TETA, it could be concluded that the organic modification with MT2EtOH is more suitable with MTHPA than with TETA.
0 wt% organo-clay nanoplatelets and of MTHPA with 6.
3 wt% organo-clay nanoplatelets in DGEBA or MTHPA were observed at around 2[theta] = 2.
73 nm, of intercalated clay nanoplatelets was obtained, whether organo-clay nanoplatelets were mixed with DGEBA or MTHPA after sonication.
Thus, the sonication technique provided better expansion of clay basal nanolayers and dispersion of individual clay nanoplatelets, even though the montmorillonite clay nanoplatelets have been organically modified with MT2EtOH before mixing with DGEBA and MTHPA.
0 wt%) nanocomposites cured with MTHPA, TETA, and POPTA.
Figure 2 also shows the glass transition temperature, which is assigned as the peak position of loss factor curve measured by DMA, of the DGEBF and the biobased neat epoxies cured with MTHPA.
