Abstract

In this paper,the regularities of graft copolymerization of n butyl methacrylate onto starch by using chromic acid as an initiator were repoted.Many effects on the grafting percentage and the grafting efficiency percentage were discussed including the initiator concentration,the monomer concentration the reacting time and temperature.The results show that the grafting percentage was higher,when monomer concentration and initiator concentration were 0.6mol/L and 5×10 -3 mol/L at 30℃ for 2h respectively.
