In order to overcome these limitations, the copolymerization of lactides with other monomers have been a widely used approach [5-6], but without any success for commercial application. Blending of PLA with other polymer is more practical and less expensive.
Hence, blending with other polyester, such as polycarprolactone, poly(butylene succinate), poly(butylene adipate)-co-terephthalate and poly(ethylene succinate), could achieve a more ductile multiphase material, by taking in to account the effect of composition on phase distribution
