High-pressure Raman spectroscopy and X-ray diffraction of THV 500, a terpolymer of tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride, were performed using diamond anvil cells (DAC). Changes in the interatomic spacing as well as shifts of several of the vibrational bands as a function of pressure were measured up to {approx}10 GPa. The changes in interatomic spacing and shifts of the vibrational bands are compared to those of polytetrafluoroethylene, showing the effects of copolymerization and reduced crystallinity. The high-pressure behavior of polymers is a relatively unexplored field but is becoming increasingly important due to applications where polymers experience extreme conditions.
