Abstract

Method for converting lactic acid (L-lactic acid and D-lactic acid) orlactic acid derivatives into polylactides, said polylactides comprising polyL-lactide, poly D-lactide, poly (D,L)-lactide and polyesters obtained fromthe copolymerisation of D-, L- and (D,L)-lactides, comprising the testing ofmolecular parameters such as the molecular weight and the molecular weightdistribution, via the controlled polymerisation of lactides primed by metalalcoholates.

Translated title of the contributionPRODUCTION SEMI-CONTINUE DE POLYLACTIDES PAR OUVERTURE DE CYCLE LACTIDES OBTENUS A PARTIR DE DERIVES D'ACIDE LACTIQUE.
