Abstract:

Solid polymerizable diacetylenic monomer compositions, including compositions co-crystallized from a diversity of solvent systems under diverse cooling conditions, can exhibit diffraction patterns associated with the color development reactivities of the compositions. High reactivity compositions are disclosed and high reactivity and low reactivity phases can be identified. A low angle powder X-ray diffraction peak can indicate the presence of one or more crystal phases in a composition. A fingerprint region can exhibit fingerprint patterns of diffraction peaks associated with different reactivities. Information about polymerization of the diacetylenic monomers is disclosed using C nuclear magnetic resonance (“NMR”) characterization. Diacetylenic monomer compositions useful in ambient condition indicators, for example time-temperature indicators are disclosed.
