Abstract

On décrit un procédé de préparation de PLA par oligomérisation et polymérisation d'acide lactique constitué au départ, en tout ou partie, d'acide lactique provenant des rouleaux contenant du PLA et ayant été utilisés comme supports de bobines de fil textile et/ou de film, ce PLA étant recyclé sous forme d'acide lactique. On décrit également l'utilisation de ces rouleaux ainsi obtenus comme support de bobines de fil textile ou de film de matière plastique.
