Features of the structure and the thermal properties of a number of fluorinated paraffins

The paper presents information obtained in the study of the morphology, molecular structure, phase composition and thermal properties of fluoroparaffins of the following grades: PPU-90, PPU-110 and PPU-180. The studied samples are fully fluorinated low-molecular polymers consisting of CF 3 (CF 2 ) n CF 3 molecular chains. In terms of morphology, samples of different grades are densely packed layered formations (particles) that differ in layer thickness, layer packing method, and particle size. Differences in the crystal structures and degree of crystallinity of the samples were revealed. The possibility of changing the morphology of fluroparaffins studied during heat treatment is shown.
