Modification of PLA by Blending with Elastomers
Different methods have been proposed to modify poly(lactic acid) (PLA) mechanical properties and to improve PLA performance in a variety of conditions and applications. Among them, plasticization, co-polymerization and blending with other polymers have been the subject of intense academic and industrial research. The addition of plasticizers has been fully detailed in other chapters of this volume. This chapter will be devoted to the PLA co-polymerization and particularly with elastomers, which could be considered as good candidates for the improvement in PLA mechanical properties.
