摘　　要：本研究以羟丙甲基纤维素、己基异氰酸酯、氮甲基吡咯烷酮等为原料,二月桂酸二丁基锡为催化剂,采用一步法,制备了一种羟丙甲基纤维素衍生物,该衍生物是一种聚氨酯材料。采用傅里叶红外光谱仪(FT-IR)对制得的聚氨酯进行了结构表征。同时,将制得的羟丙甲基纤维素衍生物溶解于氮甲基吡咯烷酮可制备得到溶剂移除沉淀型原位凝胶。In this study, hydroxypropyhnethylcellulose derivative, a polyurethane material, was directly prepared from hydroxypropylmethylcellulose, hexyl isocyanate, azomethylpyrrolidone and dibutyltin dilaurate. The structure of the derivative was characterized by Fourier transform infrared spectroscopy （FT-IR）. At the same time, the prepared cellulose derivative dissolved in N-methyl pyrrolidone could obtain a solvent-removing precipitated in-sittt gel.
