AB - Room-temperature phosphorescence of a dopant in hexamethylolmelamine and in a related condensation resin is influenced by several physical and chemical changes involving water and condensation reactions. The latter affect the degree of cure and thus the influence of humidity on the methylol-methylol hydrogen bonding of the system. The transformations involved are investigated by thermal analysis and the results correlated with the specific effects of each transformation on phosphorescence intensity Initially, the transformations involve absorbed water and water of crystallinity. The subsequent condensation reactions producing water take place in two stages: the first reaction occurs in the molten phase, the second takes place at a higher temperature in the solid state. The two stages differ distinctly, showing endothermic and exothermic behaviour, respectively. Variations in phosphorescence intensity during high humidity exposure and drying cycles confirm the significance of absorbed water in the methylol-methylol hydrogen bonding of the system. © 1979.
