Present and Future of PLA Polymers

Abstract

Lactic acid-based aliphatic polyesters (PLAs) are well known biocompatible bioresorbable polymers which are being increasingly used as biomaterials for temporary therapeutic applications. Because of their sensitivity to water and the formation of degradation by-products which can be easily metabolized by microorganisms, this type of polymers also has potential to replace commodity polymers in packagings or as mulch films. From an overview of synthesis routes, structural characteristics, and performances, an attempt is made to evaluate the future of PLA polymers insofar as industrial development is concerned.
