Abstract
The aim of this study is to determine the influence of the macrodiol chain length on the kinetics of polyurethane formation of segmented and non-segmented polyurethanes. Differential thermal analysis and the adiabatic reactor method were used to study uncatalysed and catalysed systems, respectively. The kinetic results are discussed with reference to the Arrhenius equation. The helical structure as well as the domain formation have enabled us to explain the kinetic behaviour of the carbamate formation reaction.
