| Research Abstract |
The microcrystalline cellulose (MCC) mechano cations, which were produced by heterogeneous scissions of be-ta-1,4 glycosidic linkage comprising MCC main chain due to a ball milling, initiated the cationic polymerization of isobutyl vinyl ether (IBVE) on the surface of MCC nano particle in vacuum without both protonic acid and a Lewis acid, and produced the block copolymer of MCC and polyIBVE (MCC-bock-PIBVE) during milling. This mechanochemical cationic polymerization produced chemically modified MCC nanoparticles covered with PIBVE chains of the MCC-block-PIBVE.
