Morphological studies of extruded linear polyethylene by raman spectroscopy

Abstract

The kinetics of water vapour adsorption of poly(acrylonitri1e) fibres modified by hydrazine hydrate, ethylenediamine and diethylenetriamine, respectively, is investigated. The results are explained on the base of the activity of the anion and cation exchange groups in the materials, and o n their accessibility for water vapour molecules.
