## Abstract Cellulose acetate carbamates (CACs) are the polymers which result when organic isocyanates are reacted with the free hydroxyl groups of cellulose acetate (CA). CACs are more hydrolytically stable and exhibit physical properties which are superior to those of their CA mixed ester analogs
Novel families of thermoplastic polysaccharides such as cellulose-2,5-acetate were produced by means of reactive processing technology that grafted cyclic lactones simultaneously onto polysaccharide, hydroxyfunctional plasticizer, and optionally also onto hydroxyfunctional fillers. Organosolv lignin
Metal chelates of secondary cellulose acetate (SCA) with chromium(III), copper(II), cobalt(II), niekel(II) and UO~ + were prepared and characterized by elemental analyses, magnetic moments and spectral studies. SCA acts as a uninegatively charged bidentate ligand and reacts with the metal ion via th
