Abstract
19F NMR chemical shift spectra of polytetrafluoroethylene have been obtained using an eight pulse homonuclear line narrowing multiple pulse sequence. These spectra have been obtained as a function of polymer crystallinity and temperature. The polymer crystallinity is quite precisely determined and the lineshapes allow identification of different types of molecular motion in crystalline and amorphous fractions as a function of temperature.
