A process for the continuous production of polylactide polymers from lactic acid which incorporates removal of water or a solvent carrier to concentrate the lactic acid feed followed by polymerization to a low-molecular-weight prepolymer. This prepolymer is fed to a reactor in which a catalyst is added...http://www.google.fr/patents/US5247058?utm_source=gb-gplus-shareBrevet US5247058 - Continuous process for manufacture of lactide polymers with controlled optical purity
