POLYCLORO-
TRIFLUROTHYLEME

Dielectric Research

October 26, 1959

Graph of the dielectric loss index vs. frequency for polyclorotrifluorothyleme at room temperature and selected temperatures from -50 degrees to 200 degrees C.

The degree of crystallinity in these specimens measured at the National Bureau of Standards was 80 percent.

For each temperature value, there is a frequency at which the loss factor reaches a peak.

As this frequency increases with temperature, the height of the peak also increases.
