摘要：

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 1065 cm-1 and resonance interactions in the bending (1440-1470 cm-1) and C-H stretching (2840-2950 cm-1) regions of the Raman spectra of UHMWPE at high pressure are described. The dependences of mode Grüneisen parameters (ri) on vibrational frequency (vi) were determined at several pressures from the Raman spectra and compression experiments of UHMWPE. © 1990.
