The phase transitions in crystalline C60F36 and C60F48 were found by the DSC method at 370 and 315 K, respectively. Mechanical treatment of the samples under study results in disappearance of the phase transitions. This fact correlates well with the earlier obtained data concerning the effect of mechanical treatment on the properties of low and high temperature phases of C40 and, as a consequence, on the orientation phase transition (260 K). The structural "hypersensitivity", should be taken into account in studying crystalline phase of fullerenes and their derivatives.
