Abstract Poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate-co-adipate) (PBSA) blend films were prepared with different contents of a multifunctional epoxide chain extender Joncryl ADR-4468 (ADR) or benzoyl peroxide (BPO). The long-chain-branching (LCB) introduced by ADR and branched/crosslinked entanglement induced by BPO increased melt elasticity, viscosity and compatibility, as indicated by thermal properties, rheological and morphological analyses. It was found that the elongation at break and the tensile strength were significantly improved, due to the enhancement of compatibility and the interfacial adhesion by the incorporation of ADR or BPO. The best mechanical properties were obtained in PBAT/PBSA/ADR (60/40/0.3) (A4T6A0.3) More >
