A new method of the surface modified starch (SM-St)by grafting reaction of the hydroxyl groups on the starch with L-lactic acid was developed. A novel biodegradable starch grafted copolymer, starch-g-poly(L-lactide)(St-g-PLLA), was synthesized in situ by the ringopening graft polymerization of a L-lactide (LLA)monomer onto the surface of the SM-St granules in the presence of Sn(Oct)2 as a catalyst. The PLLA grafting efficiency could reach as high as 64 wt
