Abstract :
Novel regioselective, homo-(4–6) and heterogeneous (7–10) dendronized cellulose derivatives have been prepared by the reaction of cellulose in a N,N-dimethylacetamide (DMAc)/LiCl solvent system with diverse dendrons (1–3) possessing an isocyanate focal group. The dendronized cellulose derivatives were characterized using Fourier transform infrared (FTIR), 13C NMR, thermogravimetric analysis (TGA), and dynamic mechanical thermal analysis (DMTA). These polyfunctionally coated cellulose-based materials showed diverse solubility characteristics in organic solvents ranging from DMAc to methyl alcohol.
