This study provides the first systematic investigation of the effect of aromatic and aliphatic epoxy functionalities on these reactions and their quantitative correlation with the self-blowing behavior of NIPU foams. Detailed kinetic analysis of model monomers showed significant differences in activation energy, with aromatic systems exhibiting lower activation energy, leading to faster reaction rates, while aliphatic systems had higher activation energy, indicating slower curing.
