英文摘要 | 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 ring-opening 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%. the structure of st-g-plla was characterized by ir, dsc and waxd. the good adhesion between the two components had been evidenced by sem observations. the medium-resistance of st-g-plla and the mechanical properties of the plla composite blending with st-g-plla were much better than that of the plla/starch blending composite.
