Bio-based poly(butylene succinate) (PBS) and PBS-based copolymers were blended with an aliphatic-aromatic poly(butylene terephthalate-butylene adipate) (PBAT) (Ecoflex). It was confirmed that melting temperature of new blends were similar to the neat blend components. However, for PBS/PBAT 90/10 blend we noticed higher crystallization temperature compared to the neat PBS thus demonstrating that the addition of PBAT
