摘要：

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. The soluble products can be shaped and crosslinked, forming siloxane and silanol polymer network. By incorporating tetraethoxysilane as inorganic precursor, novel silanized film can be prepared and are studied by scanning electron microscopy.
