Preparation and characterization of microcrystalline cellulose-g-methyl methacrylate by solid-state method

This paper studied on reaction rule between microcrystalline cellulose and methyl methacrylate's graft copolymerization by using APS as initiator.The effects of water content,reaction time,reaction temperature,contents of the MMA monomer and the initiator on the graft copolymerization were investigated.It is showed that graft copolyrner with higher grafting ratio and grafting efficiency was obtained when the mass fraction of water in reaction system is about 50%,MMA mass is 20%of corn microcrystalline cellulose mass,APS mass is 10%of microcrystalline cellulose mass,the reaction temperature is 80℃and the reaction time is about 40 min.The graft copolymer is characterized through FTIR,TGA and XRD.
