Abstract

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..
