  • Published:
Journal of Applied Spectroscopy Aims and scope

Abstract

The length of straightened segments of macromolecules (SSM) in unconsolidated xerogels of superhigh molecular polyethylene, which turned out to attain 18 nm, was evaluated from the position of the band of longitudinal acoustic vibrations in a low–frequency Raman spectrum. The mean length of the straightened segments of macromolecules is equal to about 11 nm.
