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.A process for the preparation of PLA is described by oligomerization and polymerization of lactic acid consisting initially, in whole or in part, of lactic acid originating from rolls containing PLA and having been used as supports for reels of textile yarn and/or film, this PLA being recycled in the form of lactic acid. The use of these rolls thus obtained as a support for reels of textile thread or plastic film is also described.
