| Abstract: | The solid phase graft copolymerization of corn starch and methyl methacrylate,butyl acrylate was studied.Infrared spectra was used to characterize the structure of the starch grafted copolymers and the effect of each factor on reaction was discussed.The optimum conditions are as follows: initiator is 7 phr,water is 35 phr,reaction temperature is 60℃,and reaction time is 50~60 min. |
| Keywords: | Solid-phase method Corn starch Methyl methacrylate Butyl acrylate Graft copolymerization |
