In the last decades poly(lactic acid) (PLA) has received great attention because of its notable properties, which make it a potential substitute for many commodity petroleum-based plastics for a number of technological applications. PLA, a linear aliphatic thermoplastic polyester, is mainly produced by ring-opening polymerization of d- and l-lactide, in turn both obtained from the fermentation of sugar feed stocks. The right weight ratio of the two enantiomers influences, among others, mechanical performances of PLA-based formulations. The aim of this chapter is to critically analyze the main limitations of PLA in terms of mechanical properties, which currently limit their use in many relevant industrial sectors, presenting various possible approaches recently proposed to overcome these intrinsic drawbacks

Abstract
In the last decades poly(lactic acid) (PLA) has received great attention because of its notable properties, which make it a potential substitute for many commodity petroleum-based plastics for a number of technological applications. PLA, a linear aliphatic thermoplastic polyester, is mainly produced by ring-opening polymerization of d- and l-lactide, in turn both obtained from the fermentation of sugar feed stocks. The right weight ratio of the two enantiomers influences, among others, mechanical performances of PLA-based formulations. The aim of this chapter is to critically analyze the main limitations of PLA in terms of mechanical properties, which currently limit their use in many relevant industrial sectors, presenting various possible approaches recently proposed to overcome these intrinsic drawbacksI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
