Title:
CRYSTALLINE POLYMORPHISM OF INCLUSION COMPOUND, CURABLE COMPOSITION CONTAINING SAME, AND CURED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2016/117298
Kind Code:
A1
Abstract:
Provided is a novel crystalline polymorphism of an inclusion compound (molar ratio 1:1) comprising 5-hydroxyisophthalic acid and 2-ethyl-4-methyl imidazole. A novel crystalline polymorphism of an inclusion compound (molar ratio 1:1) comprising 5-hydroxyisophthalic acid and 2-ethyl-4-methyl imidazole can be obtained by recrystallizing crystals obtained using conventional methods, said inclusion compound having refraction peaks at diffraction angles (2θ) of 14.68º, 16.96º, 20.36º, 23.48º, 25.92º, 26.52º, 27.84º, and 29.56º, in a powder X-ray diffraction pattern measured using a CuKα ray.
