摘要
Bead cellulose, particle diameter 0.1-2.7 mm, was prepared from dispersions of viscose in chlorobenzene by applying the thermal sol-gel transition. Technical viscose containing modifiers Berol Visco 32, Berol Glyco 1540 and Kordamin V was used. The size of cellulose beads can be controlled by means of the amount of oleic acid in the dispersion medium. The optimal result was reached at 5-6 mg oleic acid in 90 ml chlorobenzene.
