HSM-PLM images of the ketoprofen (KPR4) formulation. The polymer matrix began to solubilize the KPR crystals (yellow-golden color) at around 80 °C. Complete conversion of crystalline KPR into a molten form was observed at 97 °C. KPR in a glassy/amorphous form did not recrystallize during the cooling step. The field of view is 250 μm × 250 μm (15X).
