Description
Summary:	A systematic study of the molecular and supramolecular structural features of fluorinated paraffins has been conducted with the use of a set of physical methods and quantum-chemical calculations of the parameters of the IR and NMR spectra. The presence of nonuniformity in the morphological structures of samples obtained from different initial products has been shown. Incomplete substitution of fluorine for hydrogen during synthesis has been revealed, and the types of structural groups in which the substitution occurs have been determined. Fluoroparaffins have been found to effectively dissolve in supercritical carbon dioxide, a phenomenon that opens new fields of application for these materials.
