摘要：

Starch modified polyurethane(St-PCL) was synthesized via chemical modification of corn starch with hexamethylene diisocyanate terminated polycaprolactone. The obtained St-PCL with different grafting rates was used as compatibilizer of starch/polycaprolactone(St/PCL) blend. The structure of St-PCL was confirmed by FTIR, and the grafting rate could reach as high as 64%. In addition, a lower St-PCL amount can effectively improve the compatibi- lity of St/PCL blends. And the thermal, mechanical and hydrophobic properties of St/PCL blends could be tailored by the amount of St-PCL.
