In this paper

the capabilities of grafting acrylonitrile （AN） onto starch initiatedby Fe（III）-TU

V（V）-TU

Cr（VI）-TU

Mn（VII）-TU redox systems were compared in thepresence of sulfuric acid of different concentrations. It was shown that the grafting capabili-ty of Mn（VII）-TU is the highest in these initiating systems. Using Mn (VII-TU as initia-tor

the effects of various acids （HClO

HNO

HCl） on the graft copolymerizationof acrylonitrile onto starch were discussed

and the capabilities of graft copolymerizationof methyl methacrylate （MMA）

acrylamide （AM）

acrylic acid （AA） onto starch wereinvestigated. The experimental results show that the order of the influences of differentacids is HClO

HNO

HCl

and the order of grafting capabilities of differentmonomers grafted onto starch is MMA

AA. The structure and morphology ofgraft copolymers were studied with infrared spectroscopy and scanning electron microscopy.The size

shape and roughness of surface of the grafted starch granules are changed aftergrafting.
