Abstract A one-step process in an internal mixer was used to prepare Poly(butylene succinate) (PBS)/high-loading
modifi ed tapioca starch (30–40 wt%) blends with low glycerol content (10–20 wt% of starch) as a plasticizer. To
promote a good compatibility, two reactive agents, maleic anhydride (MA)/peroxide and methylene diphenyl
diisocyanate (MDI), were selected and compared. The mechanical properties, morphology, and Molau test of
the blends were investigated. The compatibility of PBS/starch blends was improved by both reactive agents
at the suitable plasticizer loading (glycerol 10 wt% of starch). It was demonstrated that increasing mechanical
properties resulted in good adhesion of PBS/starch interface and… More >
