description This paper reports the Raman spectra of ultra-high-molecular-weight polyethylene (UHMWPE) at room temperature and under high pressure employing a Mao-Bell type of miniature diamond-sapphire anvil cell. Davydov splitting near 1065cm -1 and resonance interactions in the bending (1440-1470cm -1) and C-H streching (2840-2950cm -1) regions of the Raman spectra of UHMWPE at high pressure are described. The dependences of mode Gruneisen parameters (ri) on vibrational frequency (vi) were determined at several pressures from the Raman spectra and compression experiments of UHMWPE.
