摘要
Starch modified polyurethane（St-PCL） was synthesized via chemical modification of corn starch with hexamethylene diisocyanate terminated polyeaprolactone. 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 compatibility of St/PCL blends. And the thermal, mechanical and hydrophobic properties of St/PCL blends could be tailored by the amount of St-PCL.
