Microwave Kinetic Study of Functional Cellulose Grafted in Homogeneous Media

The cellulose grafted copolymer was synthesized with 2-(Dimethylamino)ethylmethacrylate(DMAEMA) onto the sugarcane bagasse under microwave irradiation in homogeneous media. A homogeneous solution was obtained through dissolving cellulose in 1-butyl-3-methylinidazolium chloride ionic liquid, which the grafting polymerization initiated by radical polymerizationin, and the presence of N,Nˊ-methylenebisacrylamide as a crosslinker. During the synthesization, the optimal reaction conditions was completely in a short time, the grating ratio could be close to 100% in 20 minutes; then the kinetics equation Rg=K(AM) 1.4 (AKPS) 1.7 was established through the process, and the apparent activation energy obtained was E=66.373kJ/mol (R=0.9915) in the initial stage of the reaction. It would provide the basic theory for bagasse cellulose microwave-assisted grafting.
