Published in 2025 at "Polymers"

DOI: 10.3390/polym17141909

Abstract: Non-isothermal calorimetry is performed to study the kinetics of metal-free A2/B2-type azide–alkyne polyaddition between the dipropargyl ether of bisphenol A with different organic diazides. The diazide structure is varied to probe the effect of the… read more here.
