Use of an imidazole or a blocked isocyanate catalysts [D. Caille, J. Pascault, L. Tighzert] Summary: Reactions between a diepoxide and a diisocyanate can lead to copolymers having isocyanurate and oxazolidone rings in their chemical structure. Using Differential Scanning Calorimetry (DSC) and Fourier Transform Infrared Spectroscopy (FTIR), we have studied the influence of catalysts such as an imidazole or a blocked isocyanate on the polymer formation. We have identified the nature of the exotherms observed in DSC experiments with the aid of FTIR spectroscopy and observed the influence of the molar ratio of the functional groups and the amount of catalyst. We have compared the influence of these catalysts with results obtained previously with a tertiary amine. Springer-Verlag, 1990 Caille D.
