WebNov 14, 2024 · Abstract. The chemical modification of cellulose via sustainable pathways is highly desirable for high performance cellulose derivatives. Herein, a novel one-pot method for the etherification and self-crosslinking of cellulose is demonstrated, for the first time, by applying the mild hydroxyl–yne click reaction that occurs in a homogeneous system. WebChain reaction definition, a self-sustaining reaction in which the fission of nuclei of one generation of nuclei produces particles that cause the fission of at least an equal number of nuclei of the succeeding generation.
