Abstrakt: | There was studied a process of solid polysaccharide (2-HEC, and NaCMC) modification through substitution reaction on surface ?OH groups. This process was activated by high frequency plasma discharge applied on flat sample after its limited swelling in liquid solution of the modificant (2-nitrobenzaldehyde, and 4-nitrobenzaldehyde). There were determined an extend of substitution reaction and changes in UV-VIS and FT IR spectra as well. |
