Rezumat:

Chemical modification of natural polymers (insoluble lignin and cotton cellulose) in radio-frequency cold plasma has been
investigated. The treatments of polymers were carried out in a rotator cold plasma installation specially designed for the R.
F. plasma treatment of powdery materials (i.e. insoluble lignin) and in a statically R.F. plasma device for cotton cellulose.
Spectral, physical and chemical analysis proved the formation of the new products with improved properties.
