Abstract
Polymer alloys of poly(lactic acid) (PLA) and poly(butylene adipate/terephthalate) (PBAT) were used, and the effects of the mixing ratio of PLA and PBAT and the addition of dialkyl peroxide (compatibilizing agent) were examined. The stress–strain curves of PLA/PBAT and PLA/PBAT/dialkyl peroxide specimens were measured using the tensile split Hopkinson pressure bar (Kolsky Bar) method. The mixing ratio of PLA and PBAT and the dialkyl peroxide addition affected the stress–strain curve behavior. The dialkyl peroxide addition increased the elongation at break and changed the fracture surface to a whitened form that was markedly uneven. The elongation at break increased with increasing PBAT content.
