摘　　要：The graft copolymerization of methylacrylate onto gelatin initiated by persulfate urea redox system was studied. The effects of reaction parameters such as copolymerization temperature, copolymerization time, concentrations of initiator, monomer and gelatin on the grafting percentage( G ), grafting efficiency( E ) and total yield( Y ) were investigated. The molecular weight of PMA branch and its intrinsic viscosity were determined.The graft copolymerization of methylacrylate onto gelatin initiated by persulfate urea redox system was studied.
