    Abstract: Non-ionic water-soluble cellulose ethers modified with 3-azido-2-hydroxypropyl groups bound via an ether link are provided having a molar degree of substitution MSAHP in the range from 0.001 to 0.50. Exemplary cellulose ethers are alkyl cell doses, including methyl, hydroxyalkyl (e.g. hydroxyethyl hydroxypropyl) or alkylhydroxyalkyl cellulose (e.g. methylhydroxyethyl). Reaction products with alkyne compounds are also provided, resulting in a terminal alkyne group. The reaction of azide with the alkyne proceeds as a 1,3-dipolar cycloaddition reaction, advantageously with Cu(I) or ruthenium catalysts. A multiplicity of cellulose ethers can be obtained from the conversion reaction. Variations in the macroscopic properties can be achieved by controlled modification, ranging from increased or reduced viscosity. The reaction, taking place within a few seconds, requires only minimal catalyst. Gel formation is reversible by adjustment of the pH such that a monophasic system (high-viscous fluid) arises again from a biphasic system (gel+low-viscous water phase).

    Abstract translation: 提供了通过醚键结合的3-叠氮基-2-羟丙基基团改性的非离子水溶性纤维素醚，其摩尔取代度MSAHP为0.001至0.50。 示例性纤维素醚是烷基细胞剂量，包括甲基，羟烷基（例如羟乙基羟丙基）或烷基羟烷基纤维素（例如甲基羟乙基）。 还提供了与炔化合物的反应产物，得到末端炔基。 叠氮化物与炔的反应作为1,3-偶极环加成反应，有利地用Cu（I）或钌催化剂进行。 可以从转化反应获得多种纤维素醚。 宏观特性的变化可以通过控制修饰来实现，范围从增加或降低的粘度。 在几秒钟内发生的反应只需要最少的催化剂。 凝胶形成可通过调节pH而逆转，使得单相系统（高粘性流体）再次从双相系统（凝胶+低粘度水相）产生。
