摘　　要：The hydrophobic starch derivatives were prepared by the reaction between the dodecenyl succinic anhydrides(DDSA) and starch. The effects of starch content in water, anhydride content, pH values and temperature on the reaction efficiency were studied. Adding the anhydride to the starch slurry in pre emulsified form makes the reaction faster and more efficiently.The hydrophobic starch derivatives were prepared by the reaction between the dodecenyl succinic anhydrides(DDSA) and starch.
