Preparation and Properties of Compatibilized Poly(Butylenesadipate-Co-Terephalate)/Thermoplastic Starch Blends

Article Preview

Abstract:

Poly (butylenesadipate-co-terephalate) (PBAT) was modified by melt grafting glycidyl methacrylate (GMA) in the presence of benzoyl peroxide (BPO) in a Haake mixer; and the various properties of blends of PBAT/thermoplastic starch (TPS) using GMA-grafted PBAT (PBAT-g-GMA) as compatibilizer were investigated. The blends comprising TPS content ranged from 20wt% to 50wt%. Thermal properties and thermal stability were characterized with DSC and TGA, respectively. The morphologic results indicated that the interfacial adhesion of PBAT/TPS blends was improved by PBAT-g-GMA. In comparison with the uncompatibilized blends, the tensile properties of compatibilized blends were significantly enhanced, particularly at a high content of TPS (i.e., 40wt% and 50wt%).
