The resulting thermoplastic SBP (TSBP) was then blended with poly(butylene adipate-co-terepthalate) (PBAT) and extruded into sheets in a single process. The effects of polymeric diphenyl methane diisocyanate (pMDI) as compatibilizer and TSBP content on rheological properties, phase morphology, mechanical properties, and water absorption of the extruded sheets were studied. In comparison, dried SBP powder was also blended with PBAT by extrusion. It was found that when SBP was used as a plastic in compounding, it yielded blends with much finer dispersion of the SBP phase than when SBP was used as a filler in compounding. The dispersion of SBP in the blends was greatly improved with the addition of pMDI. The PBAT/SBP blends with fine phase morphology showed enhanced mechanical properties and moisture resistance.
