## Abstract **Summary:** The reaction of 2,4‐TDI and DEA, as an A~2~ + B^\*^B~2~ polymerization system towards hyperbranched HPUs was followed using in situ ATR‐FT‐IR spectroscopy. The decrease in intensity of the NCO absorption band of the reactive isocyanate group of 2,4‐TDI along with the format
