Abstract
The effects of the additive amount of a chain extender, with a weight ratio of 3–5 %, on stress-strain curves of poly(lactic acid) (PCL) and poly(butylene succinate-co-l-lactate) (PBSL) polymer blends were examined with a mixing ratio of PLA to PBSL of 70/30. The additive increased the elongation at break, and the strain rate decreased elongation at break.

Acknowledgment
Dynamic tensile properties of bioplastic PLA/PLBS blends were investigated experimentally using a tensile split Hopkinson bar and a universal testing machine. At low strain rate, the additive clearly but only slightly increased elongation at break. At low strain rate, stress-strain curves showed strain softening.
