Synthesis of Biopolymer-Based Precursors for the Formation of Organic-Inorganic Hybrid Materials.

Cellulose acetates can be homogeneously transferred with (3-isocyanatopropyl) triethoxysilane, yielding the corresponding carbamates containing reactive ethoxysilane moieties. The products obtained under different conditions are characterized by liquid and solid-state NMR spectroscopy. A slight hydrolysis in products of high Si-content occurs, which strongly affects the solubility of the polymers.

Recent Advances in Solvents for the Dissolution, Shaping and Derivatization of Cellulose: Quaternary Ammonium Electrolytes and their Solutions in Water and Molecular Solvents.

There is a sustained interest in developing solvents for physically dissolving cellulose, i.e., without covalent bond formation.
