Abstract:

In this study, the biodegradable blends of Thermo-Plastic Starch/Poly(Butylene Adipate-co-Terephtalate) (TPS/PBAT) and Oxidized Thermo-Plastic Starch/Poly(Butylene Adipate-co-Terephthalate) (OTPS/PBAT) were melt compounded in the presence of styrene-acrylic multi-epoxidized polymeric compatibilizer. The need for OTPS is to balance the hydrophilicity. The compatibilizer is used to enhance the interfacial properties and the phase dimensions. The TPS/PBAT, OTPS/PBAT and the compatibilizer ratio were selected as material parameters. The TPS/PBAT and OTPS/PBAT blends with and without compatibilizer were characterized by tensile, impact tests; Differential Scanning Calorimeter (DSC), Thermo-Gravimetric Analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR). The rheological behavior was investigated by means of oscillatory rotational rheometer. The morphology investigated by means of Scanning Electron Microscopy (SEM). It was founded that the multi-epoxide compatibilizer improved the mechanical and rheological properties of the blends.
