WebDec 28, 2010 · PLA is produced via polymerization of renewable products, namely lactic acid or lactide. In this work, the synthesis of PLA is done by reactive extrusion via ring opening polymerization of L,L ‐lactide using a continuous single‐stage process which is a fast and an easy method. The resulting PLA is fully characterized by solid state NMR.
