Abstract
The effect of thermal gas dynamic destruction of polytetrafluoroethylene on its microscopic and supramolecular structure and dynamic properties is investigated by IR and 19F NMR spectroscopy. It is demonstrated that thermal gas dynamic dispersing changes the structure of polytetrafluoroethylene molecules. One of the possible mechanisms of PTFE depolymerization is the formation of oligomers with terminal –CF3 and –C=CF2 groups. This forms macromolecular packing with higher ordering and with dynamic characteristics other than those inherent in standard PTFE.
