在专利文献中已经描述了纤维素材料与异氰酸酯的反应。根据一项美国专利，2-纤维素或其含有游离羟基的衍生物在叔基有机碱存在下与脂肪族或芳香族异氰酸酯反应。一项瑞士专利3描述了在添加或不添加少量吡啶的情况下用苯基异氰酸酯处理纤维素。纤维结构没有改变，但原料重量增加，产物含氮。另一位美国人。
Reactions of cellulosic materials with isocya-nates have been described in the patent literature. According to a U. S. patent, 2 cellulose or its derivatives containing free hydroxyl groups react with aliphatic or aromatic isocyanates in the presence of tertiary organic bases. A Swiss patent3 describes the treatment of cellulose with phenyl isocyanate with or without the addition of a small amount of pyridine. The cellulosic structure was not changed but the material increased in weight and the product contained nitrogen. Another U.
