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.

合成基于生物聚合物的前体以形成有机-无机杂化材料

乙酸纤维素可以与（3-异氰酸根合丙基）三乙氧基硅烷均匀转移，得到相应的含有反应性乙氧基硅烷部分的氨基甲酸酯。在不同条件下获得的产物通过液相和固态NMR光谱进行表征。高硅含量的产品会发生轻微水解，这会严重影响聚合物的溶解度。可溶产物可以被成形和交联，形成硅氧烷和硅烷醇聚合物网络。通过掺入四乙氧基硅烷作为无机前体，可以制备新型硅烷化膜，并通过扫描电子显微镜对其进行研究。
