Comparative curing kinetics and thermal-mechanical properties of DGEBA thermosets cured with a hyperbranched poly(ethyleneimine) and an aliphatic triamine

► The curing kinetics of DGEBA with Hbpei and DETA have been studied in detail. ► Excellent agreement between isoconversional analysis and kinetics modelling. ► The potential of TTT diagrams is demonstrated as a comparative tool. ► The hyperbranched structure of Hbpei slows down the process. ► Hbpei provides a higher degree of crosslinking than DETA.
