英文摘要	In this study, polycaprolactone (PCL)-diol samples of soft segment with different molecular weights were utilized to synthesiz polyurethane prepolymer (PCLPUP) and was charged in an intensive mixer to prepare starch-PCLPU-PCL composites. The impact of the polyurethane soft segments with different molecular weights on the starch-PCLPI-PCL composite systems regarding their structure and properties, were thoroughly analyzed. Results showed that the PCLPU successfully increased the interaction between the starch and PCL in the composites, and can thus be used as an effective compatilizer to improve the compatibility between starch and PCL in the resultant composites. With decreasing molecular weight of PCLPU soft segments, the isocyanate group (NCO) content in the PCLPU increased, generating more urethane covalent bonds between PCLPU and starch, thereby enhancing the interaction between starch and PCLPU interface. Again, with decreasing molecular weight of PCLPU soft segments, the physical cross-linking between the PCLPU and PCL was increased, thereby enhancing the compatibility between PCL matrix and PCLPU interface. Owing to the improvement of compatibility between the starch filler and PCL matrix, the elongation and strength at break for the composite material likewise improved after the addition of PCLPU soft segments with low molecular weight. To this effect, a PCLPU soft segment with low molecular weight was added to the starch-PCL composites system to boost the overall performance of these starch-PCL composites.
