Abstract
Kinetic study of a reaction between poly(caprolactone diol) and aliphatic isocyanate was investigated by FTIR spectroscopy. The reaction rate was obtained from analyzing the absorbance change of NCO peak (2265 $cm^{-1}$) in series IR spectra. In the results, the overall reaction between PCL and isocyanate conformed to the simple second-order law, and the rate constant increases with increasing reaction temperature. The activation energies obtained from the evaluation of kinetic data were 25.4∼30.9 kJ/mol for hexamethylene diisocyanate and 16.8∼22.1 kJ/mol for cyclohexylmethane diisocyanate, respectively.
