Abstract
AbstractThe preparation of trallyloxypyrimidine is described, together with the polymerization characteristics of this compound under differential thermal analysis conditions. The DTA curves show a doublet first exotherm near 100°C, and a singlet exotherm at 225°C. Combining the heat values obtained from the DTA curves with infrared spectral data indicates that the complex first exotherm represents a total polymerization of two allyl groups, while the second exotherm involves rearrangment to the barbiturate structure. The fact that the last allyl group does not polymerize during the second exotherm is due to the presence of a hydroxyl group in the rearranged structure. The results are compared to a previous study of the reaction mechanism of triallyl cyanurate polymerization.
