摘要

Abstract

Thermoplastic waxy corn starch (WTPS) and maise starch (MTPS) were prepared by melt blending.Furthermore

WTPS/poly (butylenes succinate) (PBS) blends and MTPS/PBS blends were prepared for investigating the effects of starch type on the morphology and viscoelastic behavior of the blends.The results showed that plasticization of waxy corn starch was more easily performed than that of maise starch and WTPS had a lower melt viscosity than that of MTPS.The WTPS/PBS blends had a better homogeneous fracture surface than that of MTPS/PBS blends.When blending ratio of TPS/PBS was 60/40

dynamic rheological behavior of the blends was mainly attributed to TPS phase and MTPS/PBS blends had higher storage modulus and complex viscosity than those of WTPS/PBS blends.When blending ratio of TPS/PBS was 40/60

PBS phase played an important role in dynamic rheological behavior of the blends and the MTPS/PBS blends in low shear rates (ω<1 r·s-1) showed more apparent solid-like dynamic rheological behavior.
