| Research Abstract |
The mechanical fracture of microcrystalline cellulose(MCC) in vacuum at 77 K resulted in the production of chain-end-type radicals of MCC(MCC mechano radicals), which were induced by scission of.-1, 4 glycosidic linkages and trapped on the MCC solid surface. A novel block copolymer of MCC and MMA(MCC-block-PMMA) was synthesized on the MCC surface initiated by the MCC mechano radicals. The chemically modified MCC nano particles covered with PMMA chains of MCC-block-PMMA was produced. The composite of chemically modified cellulose nano particles and PMMA improved its physical property. Furthermore, the transparent sheet of the chemically modified cellulose nano particles was obtained.
