Abstract
This application relates to a time-temperature indicator based on increased thermal reactivity of diacetylene upon melt recrystallization and a method of making it. A diacetylene is crystallized into a low thermal reactivity phase from a solvent system and converted into a higher thermal reactivity phase and low sensitivity to UV light by melt recrystallization.
