Inventor: KWAK SEUNG YEOP
IPC: C08G63/08
Filed: 2021-05-24
Abstract: A preparation method of cellulose derivatives prepared through a direct graft co-polymerization method according to the present invention allows thermoplastic cellulose derivatives to be prepared simply and economically, compared to a preparation method using conventional derivatization. In addition, the ionic liquid that is not environmentally toxic and can be recovered and recycled is used as a solvent to enable the cellulose to become thermoplastic, thereby efficiently enhancing poor heat processability of conventional cellulose-based materials to be applied to various fields of industries. Furthermore, the cellulose derivatives of the present invention may present the possibility of being applied in the future as a material for replacing a material for generating microplastics that have been a big issue environmentally. In the meantime, the cellulose derivatives prepared according to the present invention show efficient thermoplastic performance at lower temperature than a conventional cellulose co-polymer because a graft polymer containing a branched structure is introduced into a cellulose chain. Accordingly, the use of the cellulose of the present invention in processing a polymer can enhance economic feasibility and efficiency.
